Abstract
211,270. Gluckstein, I. Dec. 4, 1922. Switches, actuating. -The hand-operable switch 2 is automatically switched off When the door is opened but is unaffected by the closing of the door. The switch 2 is mounted on the door frame 5 and the door 1 has fixed to it a bracket 8 carry a one-way flap 6. When the door is opened the flap 6 bears against the knob 3 of the switch 2 and moves it "off." If the switch is '' on " when the door is closed the flap 6 merely rides over the knob 3, pivoting on an axis 7. In a modification the switch is mounted on the door and the bracket 8 on the door frame.
