[0002] The existing switch, because the moving contact and the static contact need to be switched on and off frequently, but in the case of a large current, due to the passage of a large current, the moving contact and the static contact may be affected. Adsorbed by the influence of current, it is not easy to disconnect, so it is very dangerous to use the switch

The invention discloses a switch with a smoothly and excellently-switchable moving contact and fixed contact. The switch comprises a base and a cover plate arranged on the base. A first terminal and a second terminal are arranged in the base. The second terminal is provided with the fixed contact. One end of the first terminal and one end of the second terminal respectively extend out from the base. The switch further comprises a push handle which moves linearly relative to the base; a through hole is formed in the cover plate; one end of the push handle passes through the through hole and extends out from the cover plate and can move axially along the through hole; the other end of the push handle is connected with the base through a main spring; the other end of the first terminal is located in the base and is provided with a moving contact sheet which rotates around this end; the moving contact sheet is provided with the moving contact matched with the fixed contact; and the push handle is provided with a pushing mechanism which pushes the moving contact sheet to rotate around the end portion of the first terminal when the push handle moves. The switch of the invention is provided with the pushing mechanism, so that smooth disconnection and contact of the moving contact and the fixed contact in a large-current use condition can be realized, and therefore, the normal operation of the switch can be ensured.
Description
technical field [0001] The present invention relates to a switch. Background technique [0002] The existing switch, because the moving contact and the static contact need to be switched on and off frequently, but in the case of a large current, due to the passage of a large current, the moving contact and the static contact may be affected. It is absorbed by the influence of the current and is not easy to disconnect, which is very dangerous for the use of the switch. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a switch with smooth and good switching of dynamic and static contacts. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a switch, including a base and a cover plate arranged on the base, a first terminal and a second terminal are arranged in the base, and a The static contact, one end of the first terminal and the second terminal ex...
