Custom Conductive Silicone Rubber Keypad

Conductive rubber buttons,also called as conductive rubber
keypad, and Silicone Button Pad, which are made of silicone
material with different conduction methods. Conductive switch
buttons includes four types conduction ways carbon pills,
conductive paint,metal pills and metal domes

Carbon pills are one kind of small elastomer piece with carbon powder The resistance is depends on the
carbon particle property Generally, carbon pill rubber keypad resistance is 10-10 Ohms. Conductive button
keypad with carbon pills are very popular because its low cost, low resistance and long life time. The
service time can reach over than 10 million
But carbon pill rubber buttons also have the disadvantages. There are very limited shapes can choose, rod,
rectangular and oval. Other shapes need custom made. but the customization costis very high as carbon pil
die cutting tool is very expensive. Second, carbon pills conductive rubber key buttons once are molded, thy
can not be reworked if there are some pills doesn'tstick to the silicone button pad Carbon pills are molded
with silicone keypad in compression molding curing.
Conductive Ink Rubber Buttons
Conductive ink is the ink contains conductive particle, like carbon. silver copper and other metal powder
Conductive ink is the most economical way in four conduction ways. Resistance is 50-350 Ohms Thicker
ink printing can reduce the resistance. Conductive ink can be printed into different shapes for rubber keypd
button.
