Third, the main points of light switch purchase
1. Look at the shell: the best switch products on the market are generally made of PC material, also called bulletproof glue. Impact resistance, high temperature resistance, not easy to change color These characteristics are very important for controlling the switch of electrical appliances.
2. Look at materials: There are three main contact materials: silver-nickel alloy, silver-cadmium alloy and pure silver. Silver-nickel alloy is an ideal contact material at present, which has good conductivity and hardness and is not easy to oxidize and rust.
3. Look at the structure: the current switch is mainly a big rocker, and its appearance and feel are better than the previous thumb type. The large rocker switch reduces the contact between the hand and the gap of the panel and prevents the accidental electric shock that may be caused by wet hands.
