Abstract

958,754. Thermal switches; snap-action switches. DIAMOND H CONTROLS Ltd. June 21, 1962, No. 23898/62. Heading H2B. A switch, comprising a contact 1c mounted on a resiliently flexible member 1 incorporating snap-action toggle means for deflecting the contact and a contact 6f mounted on a resiliently flexible member 6 for co-operating with contact 1c includes a backstop 8 mounted on member 6 to limit movement of contact 1c away from contact 6f. Pressure on a tongue 1a of member 1 in the direction of arrow A, e.g. by the end of a bimetallic strip (not shown), operates the switch, the operating point being set by means of an adjustable insulating button 7 which positions member 6. The switch resets automatically when the pressure on tongue 1a is removed. The switch is alternatively actuated by pressure on button 7. Member 6 has a stiffened portion 6b and a resilient portion 6d carrying the contact 6f such that sliding motion between contacts 1c, 6f occurs. A contact spring 9 completes an indicating lamp circuit when engaging contact 6f.
