Lights, bell and timer automation in Kenya comes down to matching the timer to two things: the supply it will sit on and the load it will switch. Get those right and the lights, bells or pumps run themselves on schedule. This guide walks through the common setups, from a plug-in unit for a fridge to a 25A DIN rail timer that can ring a school bell, and helps you decide which one fits your building.
Manhua KG316T Timer Switch with Seconds
Manhua KG316T timer switch with the widest programming range in this lineup.
What does a timer switch actually do?
A timer switch is a small relay with a clock: it opens and closes a circuit at the times you set, with no phone or internet needed once programmed. You tell it when to switch on and when to switch off, and it repeats that pattern daily or weekly.
In a Kenyan home that usually means security lights that come on at dusk, a fridge that rests for part of the night, or a fan that runs only during certain hours. On a farm it is irrigation pumps and gate lights. In a school it is the bell.
The main difference between units is not the clock but the supply they accept and how much current they can switch. A 12V DC timer cannot switch a 240V lighting circuit, and a single-phase timer cannot handle a 380V three-phase run.
No wiring at all: the plug-in timer
If you rent, or you do not want anyone opening a distribution board, the simplest option is a timer plug. It sits between the wall socket and the appliance, and you set the schedule on the unit itself.
The Manhua MET-UK is rated 16A at 230V AC, single phase, with daily and weekly programming across up to 17 settings and battery backup that keeps the schedule through a power cut. It suits fridges, lights, fans, routers and aquarium filters where there is no access to a distribution board.
DIN rail timers for lights, bells and pumps
For anything wired into the building, you need a DIN rail timer mounted inside the distribution board. This is where matching the supply matters most.
The Manhua KG316T is the most flexible in this lineup: 240V AC single phase, 25A rated load, and programming from seconds up to full weekly cycles plus a countdown mode, with up to 25 settings. Second-level programming is what makes it work for a school bell or any short, exact trigger, rather than a window a minute wide.
If your circuit runs on 12V DC instead, the ManHua MT102C is rated 16A at 12V DC with daily and weekly programming, up to 17 settings, and a compact 60 x 60 x 32mm body. It holds its schedule for up to 60 days with no power at all, which matters where outages run long.
For circuits that a single-phase timer cannot switch safely, the ManHua MT317 handles 380V AC three phase at 16A, with daily and weekly programming up to 17 settings, a backlit LCD for dim plant rooms and DIN rail mounting.
12V DC timers for solar and off-grid setups
Solar lighting and pump systems need a timer that runs on 12V DC and does not drain the battery bank it is managing. The Manhua MT619HPV is built for that: 16A at 12V DC, up to 17 daily or weekly settings, and a low power draw so the timer itself does not meaningfully deplete the bank.
It suits solar security lighting, solar streetlights, solar pump systems and off-grid LED installations. A clear LCD keeps programming simple in the field.
Random switching for security lighting
A fixed schedule has one weakness: a lamp that clicks on at exactly the same minute every night is easy to notice. The ManHua NKG-3 random timer varies its on and off times within a range you set, so the property looks occupied.
It runs 220V AC single phase at 16A, with daily, weekly and countdown programming across up to 16 programs, DIN rail mounted and battery backed. You can still run a conventional fixed schedule on other circuits at the same time.
It is aimed at holiday homes and properties left empty while travelling. If no one is watching your gate light, this is the one to consider.
What to check before you buy
Four checks save a return trip. Do them before you order, and the fitting becomes straightforward.
- Supply and phase: 220V, 230V or 240V AC single phase, 380V AC three phase, or 12V DC.
- Load in amps: the timer must carry whatever it switches, so add up the lights or pump on that circuit.
- Mounting: DIN rail for the board, plug-in for a socket.
- Programming range: seconds for bells and pulses, daily or weekly for lights and pumps.
If the load figure is close to the rating, have your electrician confirm it before installing. The product cards show the current price and the options for each unit.

Which timer suits your building?
A plug-in timer covers renters and single appliances. The KG316T covers general lighting and bell work up to 25A. The MT102C and MT619HPV cover 12V DC and solar, the MT317 covers three-phase, and the NKG-3 covers security lighting that should not look predictable.
Check your supply and load first, then pick the unit that matches both. The card below shows the current price and takes you to the full details.
One clear next step: confirm your circuit voltage and total load, then open the Manhua KG316T and check it against your board.

Frequently asked questions
A timer plug needs no wiring and sits between a socket and an appliance, while a timer switch mounts on a DIN rail inside a distribution board and needs basic wiring to install.
Yes. The Manhua KG316T programs down to seconds, so it can fire a relay for an exact short burst rather than a full-minute window.
Use a 12V DC timer with low power draw such as the Manhua MT619HPV, which is designed for solar security lighting and pump systems.
The ManHua MT102C holds its schedule for up to 60 days with no power at all, and the other units in this range have battery backup for their schedules.
No. Three-phase circuits need a three-phase timer such as the ManHua MT317, which is rated 380V AC at 16A.
