ABSTRACT:
A component, versatile pushbutton actuated electrical switch capable of breaking one electrical circuit prior to establishing a further, different electrical circuit on successive actuators of a plunger ratchet mechanism, wherein a pair of spaced contact terminals are supported on opposite sides of a moveable contact. One of the contact terminals includes a plurality of attached portions defining a generally dog-leg configuration, wherein the portions extend in at least one plane lying generally across the line of travel of said moveable contact, with the portions having longitudinal axes forming a sufficient angle to one another with respect to the plane or planes whereby one of the portions, while bending causes torsional strain in at least one of the remaining portions of the contact terminal.
