ABSTRACT:
A tease-free switch includes a plurality of electrical terminals of planar configuration disposed in spaced apart relationship upon an electrically insulating base as well as a generally planar contact plate including at least two electrical contact regions thereupon. The plate is engaged by a push-button actuated stepping mechanism so as to be alternately rotated between a position where contact between particular of the terminals is alternately established and terminated. The switch is configured so that the contact plate is constantly biased into contact with the terminals and/or the insulating surface upon which they are disposed. In this manner partial activation of the switch will not alter the condition of the electrical contacts.
