The utility model provides a full electronic program control switch, which is composed of a power circuit, a triggering circuit, a bistable circuit and an output circuit. In the utility model, an operating switch is connected between an AC power supply and a rectifying circuit, and the rectifying circuit is a full wave rectifying circuit which is composed of a C < 1 >, a D < 1 >, a D < 2 > and a C < 2 >; the bistable circuit IC triggers a bidirectional thyristor, and the bidirectional thyristor is connected in series with a load. The utility model has the advantages of small size, light weight, less power consumption, high output capability, etc.
Description
The utility model has related to a kind of electronic switch, is specially adapted to the all-electronin grammed switch.
The grammed switch of prior art, mainly by the transformer step-down, rectifying and wave-filtering is formed power circuit, and output is finished the program control output of multichannel by the relay contact switch of two on two one cuttves.Thereby volume is big, weight is heavier, cost is high, power consumption is bigger.
The purpose of this utility model is to overcome the deficiency in the above-mentioned technology, and the electronic program that a kind of volume is little, in light weight, power consumption is little, fan-out capability is big switch is provided.
The utility model includes power circuit, circuits for triggering, flip-flop circuit and output circuit etc., in AC power and by C
