High heat and temperature resistant
Ceramic switch cover plates have a excellent high heat temperature resistant ability. ceramic cover plates can be used under 2200 ℃ high temperature environment.Coefficient of thermal expansion up to 13* 10^∧⁶from 20°C -1000°C. up to 2800°C Melting point.

Wear and hardness resistant
Ceramic switch cover plates is better wear and abrasion resistant property than metal. The ceramic hardness (mohs)up to 9, HRA 80 - 90. ceramic plates hardness is not second only to diamond, but far beyond the wear resistance of steel and stainless steel.
