Kawamura Timer Switch 25A
ر.س220.00 Inclusive of VAT
The Kawamura 25A timer switch, model TM-25A, is a Japanese made mechanical time switch with a rotating 24 hour dial that turns equipment on and off automatically at times you set once.
Its most common use in Saudi Arabia is straightforward: the water pump that fills the tank, and the electric water heater. Setting the heater to run for two hours before it is needed, rather than staying energised all day, produces a real difference in the electricity bill, because the heater reheats automatically every time the water cools, including overnight and while the property is empty.
It is also used for shop, showroom and mosque lighting, signage, pool pumps, agricultural irrigation, and farm and livestock ventilation.

Why Mechanical Rather Than Digital
A mechanical timer needs no programming, no display and no menus. An electrician or homeowner opens the cover, pushes pins into the required times, and closes it. Nothing gets forgotten or mis entered, and there is no electronics to fail in the heat of a pump room or a rooftop enclosure, which matters in this climate.
A digital timer gives more flexibility, such as different schedules per weekday and finer precision, but it costs more, is more sensitive to heat and voltage fluctuation, and needs reprogramming by someone who knows how.
For a repeating daily schedule such as a water pump, a heater or shop lighting, mechanical is the more practical and longer lived choice.

Frequently Asked Questions
Q1. Is this a genuine Japanese Kawamura?
Yes, genuine Kawamura from a verified source. Copies exist in the market with identical appearance, and the difference shows in contact life and load carrying capability.
Q2. Can it run a water pump or motor?
Yes, with an important caveat. Motor load must not exceed 3000 W, and it is always better to run the motor through a contactor rather than wiring it directly to the timer, because high starting current erodes the contacts over time.
Q3. What is the difference between 25 A and 3000 W?
25 A is the resistive rating for heaters and lighting. Motor loads are rated at 3000 W, roughly 13 A, because a motor draws far more current at startup than while running.
Q4. Does it work on 220 V?
Yes, 220 to 240 V at 50/60 Hz, matching the Saudi supply.
Q5. Can I install it myself?
Installation should be done by a qualified electrician. Full load current passes through the device, and incorrect wiring is dangerous.
Q6. Can I use it for an air conditioner?
We do not recommend wiring an AC compressor directly to a mechanical timer, because repeated switching without anti-short-cycle protection can damage the compressor. Contact us before this specific application.
Q7. Is there bulk pricing?
Yes, for lighting projects, contractors, and FM companies. Contact us with your quantity.
Before you order
The Kawamura TM-25A is a simple, durable way to schedule electrical equipment. Confirm your load and load type first, and do not wire a pump or motor directly to it. Run it through a contactor and the timer will last years longer.
