Abstract

687,821. Regulating switches. GEIGER GES., W. July 12, 1951, No. 16513/51. Class 38 (v) In a switch suitable for regulating the heat of a heating pad and for attaching to the end or middle of a movable conductor, the operating lever h moves in a space i separated by a partition from the space p which contains the rotary contact member d. The lever h which has an external operating knob l is fixed to a spindle g connected by the spring e to the contact member d, movement of the lever h causing a step by step snap movement of the contact member due to the spring being tensioned and then released when the tension is sufficient to overcome the resistance between the contacts.
