Abstract

An intelligent switch system, a so called squib, for providing power to sensitive equipment, such as missiles, rockets, and the like comprises a pair of serieally connected power switches (IPSl and IPS3) which are separately and sequentially enabled and which will not deliver power from their input to their outputs unless both switches turn on. These switches are controlled by an electonic controller (U2) that is normally left unpowered, except when a trigger input is temporary applied to the controller.
