Abstract

An assembly of sealed electric switch with the water proof and antidusk functions includes mainly a shell, a sealed container to contain the entire electric switch device and some conductive wires toconnect the connecting terminals of electric switch device with the outside power line in non-interference of sealing ability to the container. The first magnetic stress device is set up in the container and it is clutched mutually with the driving lever of the electric switch device for linked action to each other as well as the second magnetic stress device is set up correspondingly at shell outer to make magnetic force attracting to each other with the first magnetic stress device for synchronous linked action to each other.

Description

technical field

[0001] The invention relates to an electric switch, in particular to a sealed electric switch assembly with waterproof, anti-corrosion, dust-proof and explosion-proof functions and low manufacturing cost. Background technique

[0002] Because the casing of general electrical switches does not have the sealing effect, the metal terminals in them are easy to be gradually corroded or covered with dust due to moisture and dust in the air, resulting in reduced sensitivity of the switch or malfunction, and even, sometimes may cause a short circuit And cause a fire accident. In addition, it is often used as a main switch and can automatically cut off the circuit breaker when the load side is overloaded. Since the internal components and circuits are not isolated from the outside world, if flammable substances such as oil stains accumulate near the switch, or At that time, the air was filled with flammable and explosive gases, and the sparks generated when opening a...
