Carbon Pill Silicone Keypad

Carbon Pill Silicone Keypad is a highly reliable human-machine interface (HMI) solution designed for industrial control panels, PLC controllers, inverters, power controllers, industrial instruments, testing equipment, and automation control systems.
By integrating conductive carbon pills on the backside of silicone keys, this keypad ensures stable electrical contact, long service life, and consistent tactile feedback, even in harsh industrial environments.
It is widely used where durability, environmental resistance, and precise operation are critical.
