1. Static switch apparatus for controlling the application of DC power from a direct voltage source to a load and comprising: a first transistor of a first polarity having an emitter, a base, and a collector with a first terminal connected to said emitter for connection to the source of power and a second terminal connected to said collector for connection to the load; a second transistor of an opposite polarity to said first polarity having an emitter, a base, and a collector; said first transistor base and said second transistor collector being interconnected; said second transistor emitter being directly connected with said second terminal; a third transistor of said first polarity having an emitter, a base, and a collector; said second transistor collector and said thrid transistor emitter being interconnected; said second transistor base and said third transistor collector being interconnected; and said third transistor base having means for applying input signals thereto.
2. The subject matter of claim 1 wherein: said first and third transistors are of PNP polarity and said second transistor is of NPN polarity.
3. The subject matter of claim 1 wherein: the static switch apparatus is connected in circuit with a direct voltage source and a load and said direct voltage source is of a polarity to forward bias said first transistor emitter in relation to said first transistor base.
4. The subject matter of claim 1 further comprising: a fourth transistor of said opposite polarity having an emitter, a base, and a collector; said fourth transistor collector being interconnected through a resistor to said third transistor base; said fourth transistor emitter being connected to a reference potential, and said fourth transistor base being connected to a third terminal connected thereto for connection to a source of on/off signals.
