Electrical switch

An electrical switch comprising first and second power terminals, each first and second terminals including spaced terminal parts, third and fourth power terminals, one terminal part of said first terminal located adjacently spaced from one terminal part of said second terminal, the other terminal part of said first terminal located adjacently spaced from the other terminal of said second terminal, a first contact located at least in part between said one terminal parts of the first and second terminals, a second contact located at least in part between said other terminal parts of said first and second terminals, said first contact being shiftable between a first position contacting said one terminal part of the first terminal and said third terminal and a second position contacting said one terminal part of the second terminal and said third terminal, said second contact being shiftable between a first position contacting said other terminal part of the first terminal and said fourth terminal and a second position position contacting the other terminal part of the second terminal and said fourth terminal, means for independently shifting said first and second contacts between their said first and second positions, said means for shifting said contacts including opposed actuators capable of independent energization, each of said actuators including a shiftable plunger part carrying a said contact, each actuator plunger part being shiftable between retracted and extended positions for shifting its carried contact between its said first and second positions respectively, and biasing means yieldable upon plunger part movement located between said contacts for normally urging each contact into its said first position.
