Whether you're renovating an HDB flat or replacing a worn socket, this guide covers the switch and socket types used in Singapore, the brands, indicative prices, and what needs a licensed electrician.
Switch types explained
- 1 / 2 / 3-gang — the number of switches on one plate (controls 1, 2 or 3 lights or circuits).
- 1-way vs 2-way — a 2-way switch lets you control one light from two locations (e.g. top and bottom of a staircase).
- 13A switched socket — the standard Singapore power outlet, often with a neon indicator.
- USB sockets — power outlets with built-in USB-A / USB-C for charging.
- Smart switches — app or voice controlled; many require a neutral wire.
HDB, condo & landed considerations
Most Singapore homes use the standard UK-style 3-pin 13A system. For smart switches, check whether your gang box has a neutral wire — many older HDB boxes don't, which limits your smart options.
Brands & finishes
Choose switches that meet the Singapore Standard (SS) and a finish that matches your renovation — white, metal, or glass-panel designs are popular.
Price (2026)
Indicative — confirm on the product page: standard 1–3 gang switches ~S$5–S$25; 13A sockets ~S$8–S$30; USB and smart switches cost more.
Installation & safety
Replacing a like-for-like switch is straightforward, but any new wiring or consumer-unit work in Singapore should be done by a Licensed Electrical Worker (LEW). Always switch off at the mains first.
Frequently asked questions
What is a 2-gang switch?
A 2-gang switch has two switches on one faceplate, letting you control two separate lights or circuits from one location.
Do smart switches need a neutral wire in Singapore?
Most do. Many older HDB gang boxes lack a neutral wire, so check before buying or choose a no-neutral smart switch.
Can I replace a light switch myself?
A like-for-like swap is simple if you switch off the mains, but new wiring or DB-box work should be done by a Licensed Electrical Worker.
