Abstract
The utility model relates to a push-button switch which includes a seat body, a push assembly, and a terminal seat. A storage tank on the front side of the seat body is combined with the push assembly. A positioning space is formed between hanging basal parts and rear pins of two connecting terminals, the two connecting terminals are arranged on the rear side of the seat body, and the positioning space is combined with the terminal seat. Two sides of a pedestal of the terminal seat are depressedly provided with recessed parts which enable the basal parts and the rear pins of the two connecting terminals to enter a limited position. Through holes which are used to enable welding pins of a luminous element of the push assembly and the rear pins of the two connecting terminals to pass through are arranged front and back on the two sides of the pedestal. When the two welding pins and the two rear pins are welded with a plurality of contacts on a circuit board, the luminous element and the two connecting terminals can be stably supported on the rear side of the seat body via the terminal seat, thus preventing the shaking and pushing of the seat body and the pins caused by the squeezing stress from the front side push assembly and the bending deformation of the bending part of the pins, and consequently preventing the soldering tin peeling from the contacts caused by deviation and the happening of contact failure, electrical connection short circuit, interruption, etc.
Description
Technical field
