Abstract

The invention provides a safe circuit selection switch. An insertion opening matched with a rotation selection tool is formed in a panel part, and a plastic selection rotating plate is arranged on a square pin part in a sleeved mode, wherein the plastic selection rotating plate rotates synchronously when a rotating main shaft rotates to achieve opening and closing selection. A plastic end cap matched with a threaded part is connected on the threaded part in a sleeved mode, a pull-back spring is connected to the outer side of the plastic end cap in a sleeved mode, and a plastic switch piece is fastened to the outer portion of the pull-back spring, wherein the plastic switch piece is matched with the plastic selection rotating plate and can be pulled back by the pull-back spring after being ejected out by the plastic selection rotating plate. According to the safe circuit selection switch, one selection tool corresponds to one selection switch, post mistake and misoperation can be eradicated completely, and true insulation can be achieved.

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, ...
