Abstract

1,028,010. Retarding action of switches. SWF - SPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU G.m.b.H. Dec. 21, 1964 [Jan. 23, 1964], No. 51876/64. Heading H2B. A switch with automatic pneumatically delayed switch-off has a housing 1 containing a bellows 2 joined at one end to an actuating slide 3. When slide 3 is pulled out by handle 4, bellows 2 is expanded, and to equalize the air pressure, air is let in through valve 5 operated by depressing button 6. Pulling out slide 3 also tensions compression spring 15, and moves a driving member 9 on slide 3 to contact surface 11<SP>11</SP> on a member 11 carrying contact bridge 10 to drive member 11 against the action of compression spring 17 to force cam 19 on member 11 over a locking member formed by leaf spring 12 so that member 12 springs into recess 21. Moving member 11 also bridges contacts 13, 14. The resetting of the switch is caused by compression spring 15 acting to compress bellows 2, the rate at which bellows 2 is compressed being determined by a valve 16 which lets the air out at a preset rate. As slide 3 moves back, member 9 moves till it contacts surface 11<SP>1</SP> on member 11. When it has applied sufficient pressure to surface 11<SP>1</SP> to overcome spring 12, member 11 is suddenly released and slid to its inoperative position, breaking the contacts by spring 17.
