Abstract

The invention discloses a power control switch, which mainly relates to the technical field of switches, and includes a fixed frame and a switch component. The switch component includes a frame body, a circuit block one, and a circuit block two; The platform drives the frame body to slide by rotating the hand crank, and at the same time as the frame body slides, it can drive the first circuit block and the second circuit block to touch each other, and finally realize the energization of the circuit.

Description

technical field [0001] The invention mainly relates to the technical field of switches, in particular to a power control switch. Background technique [0002] At present, the switches in industrial manufacturing are generally knife switches. The structure of the knife switch is simple and convenient for manual operation, but there are also some shortcomings. Manually operating the knife to make it open or close is a direct operation, and the operator is in close contact with the current. And voltage, easy to cause safety accidents, so an indirect manual switch is needed. [0003] In the prior art, the patent application number CN201711452778.6 discloses an intelligent power control switch circuit, which includes a delay control circuit, an undervoltage protection circuit, a voltage conversion circuit and an AC load circuit, a voltage conversion circuit and an AC load The loops are all connected to 220V AC, the voltage conversion circuit is connected to the undervoltage prot...
