Detailed Description

As shown in fig. 1 to 6, the metal button switch of the present invention comprises a base 1, a plastic casing 2 disposed outside the base 1, and a metal casing 3 disposed outside the plastic casing 2. And a normally open contact pin 4, a normally closed contact pin 5 and a common end pin 6 are riveted on the base 1. And a positive LED lamp pin 7 and a negative LED lamp pin 8 are arranged on two sides of the plastic shell 2. The top of the positive LED lamp pin 7 and the top of the negative LED lamp pin 8 are integrally stamped to form two U-shaped pin parts 9, and the pin parts are connected with a PCB 10 through one pin part 9 (firstly inserted into a mounting hole at the corner of the PCB 10 and then welded and fixed), and further connected with a patch LED lamp 11 arranged on the PCB 10. The pin 7 of the positive LED lamp and the pin 8 of the negative LED lamp can be 2 pins, 3 pins or 4 pins. Wherein, 2 feet are used for controlling a monochromatic lamp, 3 feet are used for controlling a bicolor lamp, and 4 feet are used for controlling a tricolor lamp.

Preferably, the plastic housing 2 is composed of a lower housing 12 and an upper housing 13, and the positive LED lamp pin 7 and the negative LED lamp pin 8 are respectively riveted to two sides of the lower housing 12. A support boss 14 is arranged in the middle of the lower shell 12, and a guide boss 15 is arranged on one side corresponding to the support boss 14. The support bosses 14 may be supported on the PCB board 10 to improve stability. An operating rod 16 matched with the guide is arranged on the guide boss 15, and the upper end of the operating rod 16 is connected with an operating button 18 through an annular ring 17.
