Selection of illuminated tact switch
Date: 2019-12-09 Author: Fucheng
The selection of illuminated tactile switches is important. The main factors influencing the quality of a waterproof tact switch are mainly determined by factors such as the protection, solderability, conduction reliability, life, feel, production process and installation size of the waterproof tact switch. How to choose?
The key to the quality of a touch switch with a light is mainly the contact of the touch switch and the contact point of the conductive part during the switch.
First, the larger the tactile switch contact, the better. There are currently three types of contacts: silver nickel alloy, silver cadmium alloy, and pure silver. Silver-nickel alloy is currently an ideal contact material. It has good conductivity and hardness, and is not easy to oxidize and rust. It is an ideal choice.
Second, the contacts depend on the material. Housing material for illuminated tact switch. The main switch brands on the market generally use PC materials. The characteristics of impact resistance, high temperature resistance and non-discoloration are very important for controlling electrical switches.
