Micro switch with diagnostic benefits enables functional safety
An addition to the successful ASQM micro switch series, the IP67 ASQMR switch from Panasonic Industry boasts resistor-based detection of failure modes.

An application’s functional safety is — first and foremost — a matter of its components’ being as failure-proof as possible. When it comes to micro switches that are a step ahead of conventional products, Panasonic Industry is offering the diagnostic ASQMR IP67 micro switch, which contains two chip resistors as voltage dividers. This feature facilitates the detection of the failure modes lead wire break or short circuits – and thus prevents the application from experiencing a serious failure or possibly causing severe damage. Setting different output voltage levels for normal versus failure mode, the ASQMR is the most compact resistor-equipped switch available on the market today.

A double clipping sliding contact design provides excellent shock- and vibration-resistance. For maximum freedom of choice, the product line contains solder or fork terminals as well as wire leads type. An array of levers  effectively facilitates use in many applications.

From locks, latches and lids in automotive constructions to industrial emergency and safety devices or smart-home or building-automation applications – the ASQMR “mini-switch” is the component of choice for everyone seeking that extra bit of next-gen component safety and long-term reliability.
