How to use it
- Modular switches and sockets clip into a plate and a mounting box of the same range; each takes a stated number of modules.
- Match the current rating to the load: lights and fans run on lower-rated switches, while geysers, ACs and other heavy appliances need a higher-rated switch and socket on suitable wiring.
- Plan the plate size from the number of modules you need, counting blanks for a tidy layout.
Installation
- Have a licensed electrician fit it, with the supply switched off at the MCB.
- Use a mounting box and plate from the same range and module size, so the parts clip together properly.
- Tighten the terminal screws on the bare conductor only; loose terminals heat up and can melt the switch.
Care and maintenance
- Switch off the supply before cleaning, and wipe the plate with a dry or slightly damp cloth; never spray liquid onto it.
- Replace a switch or socket that sparks, buzzes, or feels warm to the touch.
- Keep heavy plugs out of a socket that is not rated for them.
Buying tips
- Buy switches, sockets, plates and boxes from one range, so the modules and finishes match.
- Check the current rating printed on each module against what you will plug or wire into it.
- Sockets with shutters keep children’s fingers and objects out of the live contacts.
