Applications: Electric motor starters, control systems, control, power circuits and electrical signalling equipment. How do Auxiliary Contacts work? An Auxiliary Contact block, or aux contact, is an electromechanical device that is mounted typically to contactors. They are physically connected to the contactor, with simultaneous activation and deactivation applying to both the contact block and the contactor at the same time.

Auxiliary contacts can be installed onto contactors either by front mounting, or side mounting. This is usually clear in the shape and size of the product, but please check the compatibility of your devices. Aux Contacts are really useful devices to aid in keeping an eye on the contactor.
