Abstract

The invention provides a safe circuit selection switch. The panel part is provided with an insertion opening that cooperates with the rotary selection tool, and the square pin part is sleeved with a plastic selection switch that rotates synchronously when the rotating main shaft rotates to make the switch selection. Rotary plate; the threaded part is sleeved with a plastic plug that matches it, and the outside of the plastic plug is sleeved with a pull-back spring, and the outside of the pull-back spring is buckled to match with the plastic selection plate. A plastic switch piece that can be pulled back by a pull-back spring after coming out. The invention provides a safe circuit selection switch which is truly insulated and can prevent misoperations in series in which one selection tool corresponds to one selection switch.

Description

technical field [0001] The invention relates to the field of electrical switches, in particular to a safe circuit selection switch. Background technique [0002] The use of electrical switches in daily life is very common. Due to its particularity, its safety is very worthy of attention, especially when it is used in subways, factories and other places that need to strictly control the switching of electrical lines, its safety is mainly realized. There are two aspects, one is insulation, that is, the isolation of electricity and switches, which is related to the safety of the operator; the other is the misoperation rate, which is related to the equipment due to improper operation and misoperation caused by improper personnel management. operational safety. At present, most of the existing technologies only make plastic insulation at the front switching handle. This method cannot cope with the situation of high current breakdown, which is very dangerous. At the same time, th...
