What are the components of the toggle switch? The quality of the toggle switch can be seen from the structure. We will give you a detailed introduction in the following details.
The toggle switch mainly includes the toggle key, the switch and the shell of the electronic device for installing the toggle key. The utility model improves the uniformity of the fit clearance between the toggle key and the nested shell, and also improves the appearance grade; improves the assembly sequence and the assembly method, as well as the assembly efficiency, reduces the cost, reduces the bad rate of the assembly, and improves the use reliability of the toggle key.
The toggle switch includes a mutually connected shell and a base cover. The cavity surrounded by the shell and the base cover is provided with a push seat, a contact bridge and a terminal. The contact bridge is an integral elastic metal contact bridge. The general elastic components are springs or shrapnel, which are the industries most dependent on the touch switch and toggle switch, thus simplifying the installation procedure, simplifying the assembly of the more complicated contact bridge and elastic components in the assembly process, and simplifying the parts, so as to reduce the material cost.
Switch to see the shell material. The main switch brands in the market generally choose PC material, which is also called bulletproof glue. The characteristics of impact resistance, high temperature resistance and color resistance are very important for the control of electrical switches. The front panel and back base of a better switch are made of PC material, while the general switch will replace PC material with black nylon material on the base, so the cost can be reduced a lot.
Second, look at the contact point, which is the contact point of conductive parts in the process of toggle switch. The size of the contact depends on the size (the bigger the better), and the material. At present, there are three kinds of contacts: silver nickel alloy, silver cadmium alloy and pure silver. Silver nickel alloy is an ideal contact material at present. It has good conductivity, hardness and is not easy to oxidize and rust.
