ABSTRACT:
An actuator-switch system formed on a unitary semiconductor body is provided which is sensitive to external stimuli. The semiconductor body includes at least five layers of alternating first and second semiconductor conductivity types, with structure extending through outer layers of the body to electrically isolate and separate the actuator from the switch. Upon sensing the eternal stimuli, the actuator injects carriers into at least one intermediate layer common to both the actuator and the switch to cause the switch to change states. Preferred embodiments include a magnetic sensitive device controlling the state of a flipflop, an inverter transistor sensitive to the state changes of the flipflop, and an SCR which when triggered by the inverter transistor injects carriers into a common intermediate layer to cause a switching action. Additional embodiments include an actuator powered by a D.C. source independent of the switch, and an actuator powered by D.C. voltages derived in part from a D.C. source and in part from the full-wave rectification of an externally supplied A.C. signal, with either the switch or an auxiliary area of the body constituting a half of a full-wave rectifier bridge prior to the occurrence of a switching action.
