The toggle switch comprises a shell and a base cover which are connected with each other, and a push seat, a contact bridge and a terminal are arranged in the cavity formed by the shell and the base cover. The contact bridge is an integrally formed elastic metal contact bridge. Since the conductive switch portion of the Dongguan toggle switch provided by the present invention directly uses an elastic metal contact bridge, the original contact bridge and the elastic member are combined into one, and the general elastic member is a spring or a shrapnel, a touch switch and Dongguan. The industry to which the switch is most dependent is simplified, which simplifies the installation procedure, simplifies the assembly of the contact bridge and the elastic element in the assembly process, and also simplifies the parts, thereby reducing the material cost, and also as a whole metal part. The elastic metal contact bridge is compared with the structure of the traditional elastic element and the contact bridge. The basic principle of the toggle switch is that the structure is more solid, and can withstand repeated use for a long time and is not prone to failure or damage.

 

The same PC material, many switch manufacturers are using domestic production (even if the standard is the United States GE what is actually a domestic cooperation plant to do, but only sold by GE), and currently there is no domestic company has the ability to produce PC material, the so-called domestic production is generally reprocessed with recycled materials, so the impurities are relatively high, will be very brittle, and the heat resistance is also obviously poor. Poor Switching to Reduce Costs The front panel may not be PC-ready, with mixes or ABS instead. These materials not only have poor impact resistance and heat resistance, but also tend to be discolored and have a rough surface when they are touched.

 

The high quality toggle switch looks at the housing material first. The main switch brands in the market generally use PC materials, and PC materials are also called bulletproof plastics. The properties of impact resistance, high temperature resistance, and discoloration are very important for controlling the electrical switches. The better switch front panel and back chassis are made of PC material, and 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 contacts, which are the contact points of the conductive parts during the switching process. The first one depends on the size (the bigger the better), the second depends on the material. There are currently three main types of switch contacts in Dongguan, silver-nickel alloys, silver-cadmium alloys, and pure silver. Silver-nickel alloy is the ideal contact material at present, and its electrical conductivity and hardness are relatively good and it is not easy to oxidize and rust.
