ABSTRACT OF THE DISCLOSURE An electrical contactor device has a molded insulating body base member with at least one boss having a bore extend- ing from a contact element support surface. A stationary contact element having a generally planar plate portion and a projection extending from said plate portion adjacent, in a bent condition, to a terminal screw receiving boss is posi- tioned on the boss of said base member and the terminal re- ceiving screw is threaded into engagement with the contact element to assemble the contact element with the screw and to simultaneously bend the projection into a keyway formed in the bore to secure the contact element to the base member. A second projection adjacent the first projection is of sub- stantially greater width than the first projection and is permanently bent into a position for engagement with a shelf extending from a portion of the base member adjacent to the bore to assist in securing the contact element to the base member.
