Title: Electric Trip Switch
IPC: H01H71/10
Filed: 1967-04-11
Abstract: 1,179,034. Thermal switches; mechanical switches. DANFOSS A/S. 11 April, 1967 [29 April, 1966], No. 16471/67. Heading H1N. A snap-action switch which comprises an overcentre tension spring 3 coupling a contact arm 2 pivoted on a fixed support 7 to an actuator arm 1 pivoted on a screw 6 adjustable in support 7, and which is operable by a creeping member 13 (for example, moved by a bimetal strip), is provided with an additional manual press-button operating member 20 urged in the direction F by a spring (not shown). In the embodiment of Fig. 1, a contact 11 on arm 2 co-operates with a main contact 14 and back stop or signalling contact 15, and the member 20 has two inclined surfaces 21, 22. When member 20 is depressed the contact arm 2 is moved into a slot 23 therein, and on release of member 20 the contact 11 re-engages contact 14 (providing the member 13 has not been operated, or has restored). Thus while contact 11 is being urged towards contact 14 the member 20 provides an on-off retractive switch, while if contact 11 has been snapped over against 15 the member 20 provides a manual reset. The contact 14 is carried on a resilient blade 16 providing a short follow-up movement until arrested by a stop 19, whereby the zero-contactpressure condition is quickly traversed. In a modification (Fig. 3, not shown) automatic reset after operation by member 13 is provided by replacing the button 20 by a button (24) having a flat extension (27) in place of surface 22. This acts as a back stop in both positions of the button and prevents the contact arm 2 from snapping beyond the line of the central slot. An inclined surface (25) corresponding to surface 21 provides for similar manual on-off actuation of the switch.
