Abstract

The invention disclose a high-power push switch. The high-power push switch comprises a shell, a button, an upper contact, a lower contact, a piston rod and a piston cylinder, the button is fixed to the shell in a linear movement mode, the piston cylinder is fixed to the shell, a piston on the piston rod is located in the piston cylinder, the piston cylinder and the piston are matched to form a piston chamber, the size of the piston chamber can be changed along with movement of the piston rod, one end of the piston rod and the button are fixed together and can move along with the button, the other end of the piston rod is provided with an arc blowing port, the piston rod can linearly move in the piston cylinder after penetrating through the piston cylinder, the piston rod is hollow, so that gas in the piston chamber can be sprayed out from the arc blowing port of the piston rod after being compressed, an arc extinguishing chamber is arranged on the shell near the arc blowing port, the arc extinguishing chamber is made of a plurality of metal plates, and an exhaust hole is formed in the shell behind the arc extinguishing chamber.

Description

technical field [0001] The invention belongs to the field of circuit breaker switches, in particular to a high-power push switch. Background technique [0002] The existing ordinary button switches cannot withstand the switching of high-power electrical appliances or high-voltage circuits. Some electrical appliances need to use relays to indirectly control the on-off of the circuit, which greatly increases the cost. market. Contents of the invention [0003] In view of the above prior art, the object of the present invention is to provide a high-power push switch and a circuit breaker with a high-power push switch. [0004] The technical solution of the present invention is achieved in the following way: a high-power push switch includes a housing, a button, an upper contact, a lower contact, a piston rod and a piston cylinder, and the button is fixed on the housing in a linearly movable manner The piston cylinder is fixed on the housing and the piston on the piston rod ...
