ASQMR diagnostic micro switch

Easy and reliable failure mode detection by integrated resistors.
ASQMR diagnostic micro switch hero

Resistor-based detection of lead wire break and short circuit

Operational safety is a matter of reliable components – with contemporary and integrated monitoring, respectively detecting functions to prevent applications from crucial failures. The new ASQMR series of IP67 micro switches now allows the easy detection of lead wire break or short circuit via an installed chip resistor, which sets different output voltage levels for normal versus failure mode.
