Solid state hybrid switches have been known heretofore. For example, C. G. Chen et al U.S. Pat. No. 4,420,784, dated Dec. 13, 1983, shows one form of hybrid D.C. power controller of the relay/circuit breaker type that uses a hybrid arrangement of hard contacts and power FETs in cooperative functional combination which is especially adapted for switching 270 volt D.C. power systems in the low atmospheric pressure environments. Also, A. R. Perrins U.S. Pat. No. 3,330,992, dated July 11, 1967, shows an A.C. load energizing circuit having a pair of reverse-parallel controlled rectifiers, a first switch for applying anode voltage to these controlled rectifiers, a second switch for gating these rectifiers into conduction to establish the circuit to the load and a third switch for shunting the controlled rectifiers. A variety of zero voltage solid state switching circuits have also been known. However, these prior switching circuits have been handicapped by certain disadvantages such as, for example, being rather complex in structure with large numbers of components, insufficient contact life, current leakage in the off condition or inadequate switching performance. Accordingly, it has been found desirable to provide an improved solid state hybrid switch that overcomes the aforesaid advantages.
