How many ways do silicone keys conduct electricity?

2024-09-23

"I want the silicone buttons to conduct electricity. What are the ways?" There are a lot of customers will ask this question, let me tell you the conductive rubber key conductive way!

Conductive black particles. This conductive black particle is the most common and the most common, can be seen on many keys, usually circular, the surface is grid pattern, resistance value of about 100Ω. The shape can also be customized, requiring an additional black die for punching.

Conductive ink. Paste inks made of conductive materials (gold, silver, copper and carbon) dispersed in the binder have a certain degree of conductive properties, and when the ink is poorly dried, the resistance value will increase, so it is also necessary to bake dry under infrared light.

Gold plated grain. Conventional conductive black particles have a resistance value of about 100Ω, while gold-plated particles can control the resistance value within 1Ω. The lower the resistance value, the higher the sensitivity of the key, so gold-plated particles are often used on silicone keys with higher sensitivity requirements. Such as military keys, car keys, instruments and instruments silicone keys and so on.
