My-Com® – Precision mechanical switches

Micrometer precision: 70 times more accurate than a hair is thick!

With a repeat accuracy of 1 micron, the My-Com® remains undisputedly the most accurate and most compact mechanical switch in the world. The standard My-Com® range of the most diverse mechanical and electric types largely reflects the requirements of the market. With its extremely compact design, the My-Com® can also be easily integrated in very constrained surroundings.

Activating force
Depending on the My-Com type an activating force in the range of 30 cN to 100 cN is required to open the switch. Special versions may require up to 250 cN.

My-Coms featuring an IP 67 protection class are usually sealed with a bellow type silicone gasket.

Actuator tip
The actuator tip of a standard My-Com is made of zirconium oxyde ZrO2. Hard metal or ruby is used for a selected number of special types.
