With the light touch switch copper thickness, to enhance the current through the ability to reduce the resistance of copper itself; toughness, especially for the toggle switch socket part, not easy to deformation. Even if the toggle switch is used for a long time, it can maintain the proper clamping force, ensure that the plug sleeve and the plug are tightly connected, reduce the arc; resist oxidation and rust, reduce the increase of resistance due to corrosion and heat problem; less riveting, the most It is a good piece of copper, which further reduces the current capacity and withstand voltage of the riveting switch. The nominal current of the switch should not be less than the operating current of the electrical load.

 

Lighted touch switch Look carefully at the product packaging for detailed manufacturer or supplier address and telephone number. Try to go to regular shops with regular purchase channels to purchase branded products. 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. The same PC material, many switch manufacturers are using domestic production, but at present there is actually no domestic company has the ability to produce PC material, the so-called domestic production are generally reprocessed with recycled materials, so the impurities are relatively high, will It is very brittle and the heat resistance is also noticeably poor.
