Abstract: An auxiliary contact mechanism of a magnetic contactor includes: a contact support member having an axial recess portion formed in the center in a vertical direction; a stationary contact; a movable contact; a permanent magnet position-fixed to the contact support member and applying magnetic attractive force to restrain the movable contact so that the circuit closing position that the movable contact is in contact with the stationary contact is maintained; and a slide movable supporter having a pressing projection portion formed at a position separated apart by a predetermined distance from the movable contact when in the circuit closing position and pushing the movable contact to release the movable contact from a restrained state after a predetermined delay time has passed, when the slide movable supporter is moved downwardly upon receiving downward pressing force by the main contact slide support member.

Abstract: The present invention relates to an auxiliary contact mechanism of an electromagnetic contactor, and more particularly, to an auxiliary contact mechanism of an electromagnetic contactor capable of maximizing a time duration for which power is supplied to a magnetic coil for switching a main contact until the main contact is closed. The auxiliary contact mechanism of an electromagnetic contactor, includes: a case formed to have a box shape; an auxiliary sliding member installed above the case, and moving up and down by receiving a pressure from a main contact sliding member; an elastic member accommodated in an insertion groove formed in the auxiliary sliding member; a pressing member insertion-installed below the auxiliary sliding member, and moving up and down by an elastic force of the elastic member; and a micro switch turned on/off by the pressing member.
