Abstract
A small, versatile electrical switch suitable for the control of low current electrical devices includes a bridging contact, in the form of a thimble, telescoped over and axially slidable on a guide stud disposed between spaced coined conductor ends which are engaged by flanges of the thimble in a retracted position. A floating sleeve having radial latch dogs is rotated by sequential push operations into and out of latching engagement with the ends of circumferentially spaced holding ribs in a surrounding housing establish projected and retracted positions for the thimble. A coil spring normally biases the thimble and sleeve to a retracted position in which position the flanges of the thimble contact the coined conductor ends. A push operation rotates the sleeve latching the sleeve and thimble in a projected position wherein the flanges are out of contact with the coined conductor ends. The next push operation rotates the sleeve, disengaging the latch dogs and allowing the coil spring to position the thimble and sleeve in its retracted position at the same time making firm electrical contact between the flanges of the thimble and the coined conductor ends under the influence of the spring.
