LOW-VOLTAGE ELECTRIC DEVICE COMPRISING DEVICE OF MUTUAL MECHANICAL INTERLOCK Russian patent published in 2012 - IPC H01H9/26 

FIELD: electricity.

SUBSTANCE: invention relates to a low-voltage electric device comprising at least two contactors and mounted on a latch. Each contactor comprises a base (11, 21), installed above a fixture (12, 22), an upper cover (4) and a sliding part (13, 23), which retains contacts and is installed in the base (11, 21) as capable of reciprocal displacement. Two contactors are arranged in parallel, and both have one mechanical mutual interlock, which comprises an element (3) of mutual interlock. A shaft of the mutual interlock element (3) may rotate in a slot of the base (11, 21). By rocking the mutual interlock element (3), a ledge of the mutual interlock element (3) extends into an aperture of interlock that retains the contacts of the sliding part, thus preventing a connecting action of the sliding part that retains the contacts.

EFFECT: invention makes it possible to independently use or combine two and more contactors into a group with provision of reciprocal mutual interlock.
