Abstract
The utility model discloses a multi-circuit infrared remote-control switch, relating to power switches, and comprising an infrared remote-control emitter which is provided with a plurality of signal-emitting control switches and a plurality of an infrared signal receivers which are respectively connected with a power and a household electric appliance. The emitter generates and modulates an infrared signal; the receiver amplifies, demodulates, and shapes the infrared signal received; after the infrared signal is latched, the making and breaking of bidirectional controlled silicon; thus the corresponding electric appliance controlled switches on and switches off the power supply. The switch can simultaneously controls the making and the breaking states of a plurality of the household electric appliances only by one remote controller. The utility model which has simple structure and low cost has a same shape which is identical with the shape of the existing wall-typed switch for the convenience of replacement.
