Check the compression function of hardware springs

Also known as metal spring. It is a mechanical component that utilizes elasticity for operation. The tightening function of hardware springs mainly includes tightening springs, stretching springs, and modifying springs.
When checking various electrical switches, it can be found that one of the two contacts of the switch must have a spring installed on the outlet to ensure close contact between the two outlets, which is excellent conductivity.
Assuming poor contact, the resistance at the contact increases, the heat generated during the current passing period increases, and in severe cases, the metal at the contact may melt. The two metal pillars of the bayonet lamp head are both equipped with springs for excellent contact; As for the central metal plate of the screw socket and the metal plates for all socket connections, they are all spring plates, and their function is to make close contact on both sides to maintain excellence.

In the magnetic tape, there is a piece of Phosphor Bronze Spring, which uses the elastic force generated by its winding deformation to make the magnetic head and the magnetic tape come into close contact. There is a long Stainless Steel Spring in the stapler, which has the effect of tightening the nails on one hand, and on the other hand, after the nails on the front are pushed out, the back nails can be sent to the front for comfortable pushing out. This way, the nails can be automatically pushed to the front until all the nails are pushed out and stopped. Many machines automatically feed, and in addition, clips such as clothes clips, ballpoint pens, and the clip on the pen case all use the compression function of springs to clamp onto the clothes.
