Q1: What is the difference between single pole (SP) and double pole (DP) switched sockets like UMS 9213?
A: A Single Pole (SP) switch, like the UMS 9213, disconnects only the Live (L) wire when switched off, which is standard for residential electrical wiring in Malaysia. A Double Pole (DP) switch disconnects both Live (L) and Neutral (N) wires simultaneously for extra isolation, usually recommended for high-power appliances like water heaters or induction cookers.

A: Yes. The UMS 9213 supports up to 13 Amps at 250V AC per socket outlet. It is safe for home appliances such as refrigerators, washing machines, microwave ovens, and desktop computers, provided total load on the circuit stays within safely fused cable limits.

A: Yes, all UMS 13A switched sockets manufactured under MS 589-2 and BS 1363-2 standards feature safety shutters. The safety shutter blocks access to live contacts until an earth pin of a 3-pin plug is inserted.
