Abstract
755,328. Switch contacts; door-operated switches. HOLLINS, J. R. Jan. 1, 1954, No. 51/54. Class 38(5) A contact 26 carried by a, support 11, e.g. a vehicle door, is attached to the end of a conductor 25 passing through a shank 21 of insulating resilient material, e.g. rubber, which is a tight fit in an aperture 16 in the door. The shank 21 has a head 23 which bears against the surface of the door or which may be separated therefrom by spacers 30, as shown. A co-operating contact may be mounted on the door jamb 12 so as to form a switch.
