An electromagnetic contactor having an improved contact structure comprising a cantilever mounted contact leaf spring with the free end portion thereof longitudinally slotted into three tongues, the center one of which is bent at an obtuse angle to serve as an overtravel spring. The free end of the contact leaf spring is engaged with a linearly reciprocating actuator which flexes the center tongue toward the outer tongues upon engagement of a fixed contact by a movable contact carried by the contact leaf spring to damp contact bounce.
