Abstract

245,484. White, A. E., (Elevator Supplies Co., Inc.). Sept. 9, 1924. Quick - action switches operated by lift gates comprise a pivoted operating lever 66 connected to the gate and mounted on a spindle 64 which carries interconnected switching members in the form of metal segments 32, 34 which are secured on a substantially oval insulating member 30. Two pivoted spring pressed contact bars 26, 28 are pressed against the edge of the rotatable switch member so that in the position shown in Fig. 1 the circuit is completed but as the spindle 64 is rotated by opening the lift gate the projecting portions 40, 42 of the member 30 force the bars 26, 28 outwardly away from the conducting segments 32, 34, so breaking the circuit and quickly extinguishing the arcs produced.
