ABSTRACT:
A three-position floating beam armature switch includes a hollow housing, in which a floating beam armature is resiliently biased toward the closed top of the housing. An operator member is carried by the housing to apply a predetermined force to the armature; so that a first end of the armature initially moves toward the bottom of the housing by pivoting the armature about its second end. Continued application of additional force by the operator member, causes the armature to pivot about the first end; so that the second end then moves toward the bottom of the housing. With both the first and second ends at the bottom of the housing, the third position of the switch is attained. Release of force by the operator member allows the floating beam armature once again to be biased toward the top of the housing to the initial position.
