Timer Switch Guide for Pakistan — Types, Wiring and Prices

If you run motors, pumps, geysers, or any load that needs to turn on and off at set intervals, a timer switch is the most cost-effective automation tool you can install. In Pakistan, digital timer relays like the DH48S series have replaced old mechanical timers in industrial panels and even home DB boxes. This guide covers every type of timer available, how to wire them, and current prices from CNC Electric Pakistan.

Quick Answer: A CNC DH48S digital timer relay starts at Rs.2,200 in Pakistan. It covers time ranges from 0.01 seconds to 99 hours, works on 220V AC or 24V DC, and fits a standard DIN rail. Shop CNC timers here →

What Is a Timer Switch?

A timer switch is an electrical device that controls a circuit based on time. You set a delay or interval, and the timer energizes or de-energizes a relay output when that time elapses. In simple terms, it is an automatic ON/OFF switch controlled by a clock instead of your hand.

Pakistani buyers need timer switches for several practical reasons:

• Load shedding management — auto-start generators or UPS changeover after a set delay
• Motor protection — star-delta starters need a timed switchover (typically 5–10 seconds)
• Energy saving — run geysers, water pumps, or lights only for the required duration
• Process control — industrial machines need precise ON/OFF cycles for mixing, heating, or conveyor movement
• Pump automation — fill overhead tanks automatically with a timer + contactor combination

Types of Timer Switches Available in Pakistan

There are three main categories of timers sold in the Pakistani market. Here is what each type does and where it fits best.

1. Digital Timer Relay (DH48S Series)

The digital timer relay is the industry standard for panel-mount applications. CNC Electric manufactures the DH48S series, which is the most popular timer relay in Pakistan. It has a digital LED display, DIN-rail mounting, and an 8-pin or 11-pin relay base. You get precise time setting from 0.01 seconds up to 99 hours using thumb-wheel switches or digital buttons.

Best for: industrial panels, motor starters, generator delay circuits, conveyor automation, packaging machines.

2. Mechanical Timer

A mechanical timer uses a spring-wound or synchronous motor mechanism. You turn a dial to set the time. These are cheaper (Rs.500–1,500) but far less accurate and have a limited time range. Common in older geyser controls and simple lighting circuits. Not suitable for industrial use.

Best for: home geyser on/off, simple lighting schedules, low-budget applications.

3. Programmable Timer (Weekly/Daily)

A programmable timer allows you to set multiple ON/OFF events across a day or week. These are typically used for street lighting, signboard control, and scheduled irrigation. CNC Electric offers the AH2N series which provides programmable features alongside relay output.

Best for: street lights, shop signage, irrigation systems, scheduled HVAC control.

DH48S-S vs DH48S-2Z — Comparison Table

CNC Electric sells both variants of the DH48S. Here is how they differ:

Feature	DH48S-S (Cycle Timer)	DH48S-2Z (Dual Delay)
Output Contacts	1 set (SPDT)	2 sets (DPDT)
Operating Mode	Repeat cycle (ON → OFF → ON)	Single delay or dual delay
Time Range	0.01s – 99h	0.01s – 99h
Supply Voltage	220V AC / 24V DC	220V AC / 24V DC
Contact Rating	5A @ 250V AC	5A @ 250V AC per contact
Pin Configuration	8-pin base	8-pin base
Best Use Case	Repeat ON/OFF cycles (e.g., mixing)	Single delay (e.g., star-delta starter)
Price (PKR)	Rs.2,200	Rs.2,400

Which one should you buy? If you need a repeating cycle (ON 10 seconds, OFF 5 seconds, repeat), choose the DH48S-S. If you need a one-shot delay or a star-delta timer, the DH48S-2Z is the right pick.

Timer Switch Applications in Pakistan

Here are the most common ways Pakistani electricians and engineers use timer switches:

Motor Control

In star-delta motor starters, a timer relay switches the magnetic contactor from star to delta configuration after 5–10 seconds. The DH48S-2Z is ideal for this. Without a timer, you risk high inrush current damaging the motor or tripping the circuit breaker.

Pump Automation

Set the DH48S-S to run a water pump for 30 minutes, then stop for 2 hours, and repeat. Pair it with a CNC contactor (CJX2 series) and you have a fully automatic water filling system. No float switch needed for basic scheduling.

Geyser Timer

Pakistani households spend significant electricity heating water. Install a timer switch on your geyser circuit to run it for 20–30 minutes only. A DH48S-S set to single-shot mode will turn the geyser off automatically.

Lighting Control

Use a programmable timer for shop signage, outdoor lights, or staircase lighting. Set it to turn on at sunset and off at midnight. Saves energy and removes the need for manual switching.

Generator Delay

When mains power returns after load shedding, a timer relay adds a 30-second to 2-minute delay before switching back to mains. This protects equipment from voltage fluctuations during power restoration. Often used with a voltage protector for double safety.

Industrial Panel Automation

In industrial control panels, timer relays sequence multiple operations — conveyor belt start/stop, oven heating cycles, packaging machine intervals, and compressor duty cycles. The DH48S series handles all of these inside a standard DB box or panel enclosure.

How to Wire a Timer Relay in a Panel

Here is a step-by-step wiring guide for the CNC DH48S digital timer relay. This applies to both DH48S-S and DH48S-2Z models.

Wiring tips for Pakistani electricians:

• Always use the timer relay output to drive a contactor coil, not the load directly. The 5A contact rating is not enough for motors above 1 HP.
• Mount the timer and its 8-pin base on DIN rail inside the panel or DB box.
• Use a miniature circuit breaker (MCB) on the timer supply line for protection.
• Label the timer settings on the panel door so operators know the set time without opening the panel.
• Keep the timer away from heat-generating components — operating temperature is –10°C to 50°C.

Time Setting Ranges

The DH48S series offers extremely flexible time settings using a combination of a dial and range selector:

Range Position	Time Range	Typical Use
0.01s – 99.99s	Hundredths of a second	High-speed packaging, solenoid pulse
0.1s – 999.9s	Tenths of a second	Star-delta transition, conveyor steps
1s – 9999s	Seconds (up to ~2.7 hours)	Pump run time, geyser heating
0.01m – 99.99m	Minutes	Oven cycles, irrigation, mixing
0.1m – 999.9m	Minutes (up to ~16.6 hours)	Generator duty cycle, long delays
1h – 99h	Hours	Multi-day process, aging test

This range — from 10 milliseconds to 99 hours — covers virtually every timing application in both domestic and industrial settings.

How to Choose the Right Timer Switch

Selecting the correct timer for your application depends on these factors:

1. Supply Voltage: Most Pakistani panels use 220V AC. If your control circuit is 24V DC (common in PLC panels and solar systems), order the 24V DC variant.
2. Time Range Needed: If your application needs sub-second precision (packaging, solenoid), make sure the timer supports the 0.01s range. For longer applications like pump scheduling, the minute/hour ranges are more appropriate.
3. Output Rating: The DH48S relay outputs are rated 5A at 250V AC. For any load above 5A (motors, heaters, large pumps), you must use the timer to drive a magnetic contactor rated for the load.
4. Number of Outputs: Need one relay? DH48S-S. Need two independent relay outputs? DH48S-2Z.
5. Operating Mode: Cycle (repeat) mode for continuous ON/OFF? Choose DH48S-S. Single delay for one-shot timing? Choose DH48S-2Z.
6. Mounting: All CNC timers use standard 8-pin bases and mount on 35mm DIN rail. Make sure your panel or DB box has space.
7. Environment: Operating temperature range is –10°C to 50°C. For outdoor enclosures in Pakistani summers (45°C+), ensure proper ventilation.

Timer + Contactor Combination for Motor Control

The most common real-world setup in Pakistan combines a timer relay with a magnetic contactor. Here is how it works:

This setup is used across Pakistan for:

• Automatic water pump control (30 min ON, 2 hours OFF)
• Star-delta motor starting (7-second delay then switchover)
• Compressor duty cycle management
• Industrial oven heating cycles
• Exhaust fan scheduling in factories

Cost of a complete timer + contactor kit: CNC DH48S-S (Rs.2,200) + relay base (Rs.350) + CNC CJX2-18 contactor (Rs.1,800) = approximately Rs.4,350 for a complete automated motor control setup.

What is a timer switch used for?

A timer switch is used to automatically turn an electrical load on or off at preset times — for geyser scheduling, water-pump cycles, street lighting, billboard control, motor start delays, generator delay timers, lighting dim-down, and industrial process automation. The CNC DH48S series handles delay-on, delay-off, cycle, and interval modes for 0.01 seconds to 99 hours range.

Do electric timers use much electricity?

No — a typical digital timer relay like the CNC DH48S consumes about 2-3 watts continuously, costing roughly Rs. 30 per month if left running 24/7. Compared to the load it controls (a 2 kW geyser, a 1.5 kW water pump), the timer's own consumption is negligible. Mechanical (motor-driven) timers consume slightly more (~5-8 W) due to the synchronous motor.

How do I install a timer switch?

Switch OFF upstream power at the DB box. Mount the timer relay on the DIN rail or in its panel cutout. Wire 220 V AC to the supply terminals (pins 1-2 on DH48S). Connect the load (contactor coil for motor/heater loads) between the common (COM) and normally-open (NO) terminals. Set the time using the front-panel rotary switches or digital display. Restore power and verify the timer cycles correctly. Always use a contactor between the timer and any load above 5 A — the timer's relay contacts are rated for control duty, not heavy load switching.
