Abstract: This invention provides an electrical switch which has regenerative ON and OFF switching and which is latched. The switch has a main switching transistor, a latching transistor, a plurality of auxiliary current enhancing transistors and a switch-off transistor. The base and collector of the latching transistor are connected with the collector and base respectively of the main transistor to act as a latch. The auxiliary transistors are connected in parallel with the latching transistor, with the bases and collectors of the auxiliary transistors connected with the latching transistor's collector, and with the emitters of the auxiliary transistors and the latching transistor being connected. Finally, the switch-off transistor is connected across the base emitter junction of the main transistor.
