Metal shrapnel (also known as pot or metal dome, snap dome) is made of ultra-thin (0.05mm-0.1mm thick) and ultra-thick (generally high hardness) stainless steel 301 or 304 Made of. Metal shrapnel is an important part of the switch. Metal shrapnel is mainly used in membrane switches, contact switches, PCB boards, FPC boards, medical devices and other products Yes. Working principle:
The metal shrapnel on the film key is located at the conductive part of the PCB board (most of it is located above the gold finger on the circuit board). When pressed, the center point of the shrapnel is concave and contacts the PCB The circuit forms a loop, the current passes through, and the whole product can work normally
General conventional metal shrapnel can be divided into round metal shrapnel, cross metal shrapnel, triangular metal shrapnel and oval metal shrapnel according to their different shapes. Diameter from 3mm to 20mm The strength ranges from 100g to 600gf. Of course, if you have special requirements to make according to your drawings, there is no problem
In addition, according to the requirements of customers for resistance, our metal shrapnel also has various surface treatments such as nickel plating, silver plating, gold plating and so on.
