Abstract: An electric switch assembly including a multipolar quick-assembly appliance and a quick-connect appliance, wherein the body of an appliance, or its power terminal strip, is directly fixed and interlocked with to the body of an adjacent appliance. The interconnection between the various appliances is rapidly performed by multipolar blocks capable of being pressed on the front surfaces of appliances and being elastically plugged into their terminals.

Abstract: The invention relates to an electromechanical contactor, comprising a mobile push-piece which is connected to the contact support and can be accessed via a front face. A cover in the form of a plate is removably mounted on the front part (10a) of the housing (10), on fastening elements (17,19) provided for mounting an additional bloc. Said cover provides a means of masking the mobile push-piece (16) and has a transparent section (21) in front of the push-piece which prevents it from being activated manually without altering the ability of the device to display the state of the contactor.
