ABSTRACT:
A contact indicating switch includes an actuator body with an upper body portion pivoted to an insulating seat body and a smaller lower body portion. The lower body portion has a downwardly opening bore that terminates at an abutment seat, and a slit communicated with the abutment seat. A biasing spring is received in the bore, and has an upper end with a finger portion extending outwardly of the slit, and a lower end biasing a rolling member to slidably engage an electrically conductive lever between a right position, where a contact end of the lever engages a right electric contact member in the seat body, and a left position, where the contact end disengages the right electric contact member. An electrically activated indicator is received in the upper body portion, and has a first terminal extending downwardly and outwardly of the upper body portion to contact a left electric contact member, and a second terminal extending in the receiving chamber. A current limiting element is received in the receiving chamber, and has an upper end abutting against the second terminal and a lower end urged by the finger portion of the biasing spring.
