Problems solved by technology

[0003] However, when the circuit switch is closed, electric sparks will occur, and a large amount of heat will be generated at the same time. These heats will ablate the contact points of the switch. After several times of ablation, the switch will be scrapped and cannot be used.
If the conduction current of the circuit is small, the ablation is not very obvious. If the current of the circuit is large, it may burn out soon and become unusable.

Abstract

The invention discloses a heavy-current long-lifetime switch. The switch comprises a circuit input end connector, a circuit output end connector, a switch trigger, a switch housing and heat conducting insulation liquid. The circuit input end connector is connected with an input circuit. The circuit output end connector is connected with an output circuit. One end of the switch trigger is connected with the circuit input end connector and the other end is connected with the circuit output end connector. The interior of the switch housing is filled with the heat conducting insulation liquid which is capable of effectively adsorbing heat generated by electric sparks. Thus, contacts of the switch are protected and service lifetime of the heavy-current switch is remarkably prolonged.

Description

Technical field [0001] The invention relates to a switch, in particular to a high-current and long-life switch. Background technique [0002] The switch is an important component that connects the conduction of the circuit. When the switch is closed, the circuit is turned on, and current flows in the circuit. When the switch is opened, no current flows in the circuit. [0003] However, when the circuit switch is closed, an electric spark phenomenon will occur. When the electric spark is generated, a large amount of heat will be generated. This heat will ablate the contact point of the switch. After several ablation, the switch will be scrapped and unusable. If the circuit conduction current is small, this kind of ablation is not very obvious, if the circuit current is large, it may burn out soon and become useless. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a high-current long-life switch, which can significantly impr...
