Abstract

962,729. Thermal switches. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. April 26, 1961 [May 25, 1960], No. 15086/61. Heading H2B. A slowly-moving actuator, e.g. a thermal capsule 3, bears on a spring-urged lever 5 pivoted at 6 and connected via a snap-acting tension spring 13 to a further lever 11. The latter co-operates with a U-shaped end 17 of a contact lever 14 pivoted at 15 and controlled by a snap-spring 20. Biasing spring 7 is adjustable by a cam 23, and end 17 has an adjustable stop 19.
