Zusammenfassung:The utility model provides a remote control electric power switch. A structure of the remote control electric power switch comprises a wireless emitter, a wireless receiver, a contactor, an air switch, a heat relay and an intermediate relay, wherein the wireless emitter is used for emitting a high frequency switch signal, and the wireless receiver is used for receiving the high frequency switch signal emitted by the wireless emitter to drive the contactor in an electrical equipment control loop to realize switch motion. According to the remote control electric power switch, the air switch can realize tripping operation for short circuit protection when equipment is in short circuit; overload protection can be realized through the heat relay when the load current is too large; open-phase protection can be realized through matching of the intermediate relay and the contactor when a three-phase power supply loop is in an open-phase state. The remote control electric power switch has advantages of reasonable stru
