Abstract

A modular switch assembly comprises a multiple switch configuration operated by a single finger. The assembly consists of a base member with a push-button or plunger switch located on its top. Four upright switch operators extend above the surface of the push-button switch for contact by movement of a finger in any of four directions 90.degree. angularly offset from one another. These upright switch operators normally are magnetically biased to a first position, located near the push-button switch. They are operated by the finger to a second position, by rocking them outwardly from the first position. All of the parts snap fit together; and there are no mechanical springs or hinge assemblies to hold the various switch parts together. Movement of any of the switch operators, from a first position to a second position, is sensed by means of a light-source/photocell combination, the light path of which is blocked when the switch operators are in one of the two positions, and which is opened when the switch operators are in the other of the two positions.
