Abstract
550,797. Press button switches. ARROW ELECTRIC SWITCHES, Ltd. June 19, 1942, No. 8424. Convention date, July 11, 1941. [Class 38 (v)] In a switch operating both by pushing and pulling from a normal position, two bridging bars 20, 40 are slidable on a reduced part of a spindle 18 and held apart by a spring 36. The spindle can be pushed or pulled by the knob 14, pushing separating contacts 22, 24 from fixed contacts 26, 28, and pulling causing contacts 42, 44 to engage with contacts 46, 48, while contacts 22, 24, 26, 28 are still engaged. The moving contacts are spaces apart more widely than the fixed contacts. The spindle rests, owing to the opposed springs 16, 36, in a central position but may be retained m either extreme position by the engagement of a pin 58 in a bayonet slot 55.
