Problems solved by technology
However, in actual production practice, the ideal working conditions set by the knife switch do not exist in many cases.
For situations where the accuracy of the dynamic and static contact direction is poor and the carrying current requirements are particularly large, the knife-plug switch often cannot be accurately inserted into the static contact slot due to the excessive position deviation of the moving contact, resulting in the failure of the knife-plug switch and excessive conductive contact area. Small can not carry too much current, can not be used normally

Embodiment Construction
[0014] Embodiments of the invention are described in detail below, but the invention can be implemented in a number of different ways as defined and covered by the claims:
[0015] Such as figure 1 As shown, the present invention provides a touch switch device capable of carrying a large current, which includes a plurality of switch units, and the switch units include movable components and stationary components.
[0016] The movable assembly includes a copper rod moving contact 1 and a buffer assembly arranged on the copper rod moving contact 1. The copper rod moving contact 1 can move relative to the buffer assembly; the stationary assembly includes a copper rod static contact 2 and a buffer assembly arranged on the copper rod moving contact 1. The fixed component on the copper pole static contact 2; the copper pole moving contact 1 can touch the copper pole static contact 2.
[0017] The buffer assembly includes a steel guide sleeve 3, an insulating washer 4, an insulating...

Description
technical field [0001] The invention relates to the technical field of switches, in particular to a touch switch device capable of carrying super large current. Background technique [0002] High-current switches are often used in the field of power supply and consumption. Traditional high-current switches are generally in the form of knife-insert switches. In general, there is no problem with the knife switch. However, in actual production practice, the ideal working conditions set by the knife switch do not exist in many cases. For situations where the accuracy of the dynamic and static contact direction is poor and the carrying current requirements are particularly large, the knife-plug switch often cannot be accurately inserted into the static contact slot due to the excessive position deviation of the moving contact, resulting in the failure of the knife-plug switch and excessive conductive contact area. Small can not carry too much current, can not be used normally....
