Description

[0002] In modern industry and electronics, high-current metal switches play a vital role. They can withstand high current loads and ensure the normal operation and safety of circuits.

[0003] Self-locking push button switches are commonly used electrical connectors on many mechanical equipment or devices. Their function is to control the on and off of circuits. Large current metal switches generally use self-locking push button switches, but the self-locking push button switches currently on the market do not have a waterproof function. As a result, water vapor will enter the interior of the self-locking push button switch, which will easily cause the conductive sheet inside the self-locking push button switch to rust. In addition, the load-bearing capacity is not high and it is easy to be damaged, and even cause electric shock accidents. At the same time, it is impossible to achieve a large current impact of 20A, and the switches currently on the market can generally withstand a voltage of 1000V-1500V, and the withstand voltage value is relatively low.
