MJ3 Series Microswitches – Contact Reliability Note:
Many common Microswitches have standard SPDT contacts, similar to our MJ2 Series products. These
switches are “tried and true” – yet, there is a more reliable switch now available for high reliability
applications. This new product, MJ3 series, has a low contact resistance due to the double contacts and
an expected very low failure probability. For the standard SPDT microswitch, if the commutation failure
(FC) is approximately one in every 10,000 – the dual contact MJ3 series products have a failed commutation of
approximately 100,000,000.
In addition, the MJ3 series products are all supplied with positive opening contacts. This is an additional
reliability feature (safety) which allows for a rigid connection between the plunger of the switch and the
NC contacts which will forcibly open the contacts in the event of contact closure by electrical over-load.
