Abstract:
Switching system for controlling an electrical first circuit in which high voltage is utilized for energizing a load in the circuit, and having a main switch in the first circuit, comprising,a low voltage second circuit, a transformer operatively connected between the circuits for providing low voltage in the second circuit, a 7414 inverter operatively interconnected between the high voltage circuit and the low voltage circuit, and a plurality of manual toggle switches in the second circuit, each toggle switch including, a frame having spaced contact posts for connection with electrical conductors, a conducting leaf spring secured at a first, fixed, end to a first of the contact posts, and carrying a movable contact element at a second, swinging, end adjacent the second of the contact posts, the leaf spring being self biased to a position wherein the movable contact element is in a CLOSED position relative to the second of the contact posts, the leaf spring having a straight portion with segments adjacent its ends, and a bowed element between such segments, the toggle switch including a lever pivoted on the switch frame and having a point engagable with either the straight portion, or the bowed element, of the leaf spring, but not both, and operable, upon manual swinging of the lever at each of the opposite ends, for moving the swinging end of the leaf spring into CLOSED position relative to the second of the contact posts.
