Abstract
A dc power switch responsive to an input signal referenced to a signal reference terminal and having a power input terminal connected to a dc voltage source and a power output terminal connected to a load. The dc switch has an isolated voltage source referenced to the signal reference terminal; a current limiting resistor; and a two-pole switching circuit for coupling the isolated voltage source to the current limiting resistor. An output switching circuit couples current from the voltage source via the conduction channel to the signal reference terminal. A sense resistor has a first terminal coupled to the signal reference terminal and a second terminal coupled to the power output terminal. A SCR switching circuit latches into a conducting state in response to the firing signal and shunting current from the isolated source via the current limiting resistor second terminal to the power output terminal thereby shunting the control signal high state to a control signal low state in response to the firing.
