Description

Snap-type rotary switch base Technical Field

[0001] The present invention relates to the technical field of switches, in particular to a snap-on rotary switch base.

Background technique

[0002] A switch is an electronic component that opens a circuit, interrupts current, or causes it to flow to other circuits. The switch is widely used in various electrical equipment. The most common switch is an electromechanical device that is operated by people, of which one or several Electronic contacts can be divided into knob switches, toggle switches, button switches, key switches, membrane switches, point switches and other types of switches.

[0003] At present, the rotary switches in the industry are designed with holes in the plastic base. The copper terminals are inside the plastic parts. The wiring method is: the power cord is peeled and tinned, and then inserted into the base to connect. The disadvantages of this structure are: 1 . The wire is inserted into the base, and it is not firmly clamped by the plastic and copper parts, and it is easy to fall off; 2. Tin is easy to blacken and oxidize, the resistance value becomes larger, the temperature rises, and it is easy to catch fire.
