Patent number: 5595289Abstract: A rocker-type electrical switch of the kind known as a "quiet switch" includes a manually depressible rocker having two opposed contact surfaces at a small angle to each other from which rocker depends a rocker arm terminating in a rocker cam. A slider positioned intermediately of the rocker and the rocker cam is moved back and forth by side-to-side movements of the rocker arm and opens and closes one or more pairs of contacts. Rocker movement is controlled by a rocker cam leaf spring engaging the rocker cam which spring has a cammed profile traversed by the rocker cam to slow the switch, lock the rocker and provide other desirable effects. The rocker cam spring is housed in a spring chamber longer than itself, allowing the rocker cam spring to float.Type: GrantFiled: August 31, 1995Date of Patent: January 21, 1997Inventors: Stephen R.

Patent number: 5543596Abstract: A rotary switch operated by a cam having a lobe is disclosed. The cam is attached to a mechanism for rotation about the axis of the cam. A first switch contact member is positioned adjacent said cam and selectively makes electrical contact with a second switch contact member. The bracket attached to the first switch contact member contains a roller positioned adjacent to the cam for rotatably engaging the cam as the cam rotates. The roller is positioned with the bracket portion of the first contact such that the axis of the roller is movable from a first position to a second position as the switch changes from an open to closed or from a closed to open position. The bracket may contain an elongated slot which permits the axle of the roller to move within the slot as the switch changes modes. The slot preferably extends linearly and at an angle less than 45 degrees from a tangent line to the surface of said lobe adjacent the slope between said cam and said lobe.Type: GrantFiled: August 16, 1994Date of Patent: August 6, 1996Assignee: Union Switch & Signal Inc.Inventors: Richard S. Jones, William H. Hodges, Jr., Paul M. Evans

Patent number: 5468926Abstract: A switch device includes a conductive plate which is embedded in a housing of a synthetic resin and has one end projecting from the housing. A substantially V-shaped movable contact is supported at the one end of the conductive plate. An urging pin is carried on an operating member swingable about an axis parallel to an axis of swinging movement of the movable contact and is resiliently brought into abutment against the movable contact. In such switch device, support sections are integrally provided on one of inclined portions of the movable contact for receiving one end of the conductive plate which is formed into a non-bent flat plate-like configuration. Thus, it is unnecessary to conduct the bending of the conductive plate, and the movable contact can be swingably supported at the one end of the conductive plate, leading to an enhanced assembling efficiency.Type: GrantFiled: April 26, 1994Date of Patent: November 21, 1995Assignee: Toyo Denso Kabushiki KaishaInventor: Hiroshi Sato

Patent number: 5436421Abstract: A two pole electrical switch has side-by-side movable contacts operated by a single rocker/actuator of the type having side-by-side pin recesses. Two pins in these recesses are spring biased toward the movable contacts to achieve contact closing, but one pin has its end offset from the other pin end so the closing is sequential rather than simultaneous.Type: GrantFiled: April 13, 1994Date of Patent: July 25, 1995Assignee: Carlingswitch, Inc.Inventor: Walter A. Sadowski

Patent number: 5391847Abstract: In an electric switch, a movable contact element (6, 106) is linked to a first fixed contact (3, 103) by an end portion (14, 114) having a sharp-edge outline and housed in a seating having a rounded outline. The movable contact element (6, 106) has an interconnecting portion (9, 109) provided with a frusto-conical projection to be engaged in a coupling opening (18, 118) having rounded edges and formed in a second fixed contact (4, 114), so as to establish an electric continuity between the first and second fixed contacts when the movable contact element (6, 106) is brought to a closed condition. A first silver insert (16, 116) is joined on the interconnecting portion (9, 109), which insert has a larger volume than a second silver insert possibly joined on the edges of the coupling opening (18, 118).Type: GrantFiled: July 19, 1993Date of Patent: February 21, 1995Inventor: Cesare Gallone

Patent number: 5336861Abstract: A switch is provided with a button frame which has two openings and two associated cam surfaces. A pivot pin can be assembled with a support structure and the button frame can be assembled onto the pivot pin by distorting the button frame. One end of the pivot pin is first inserted into a first opening of the button frame. Then the button frame is pushed downward to cause a second end of the pivot pin to move along a cam surface associated with a second opening. Further downward force causes the second end of the pivot pin to snap into the second opening.Type: GrantFiled: April 28, 1993Date of Patent: August 9, 1994Assignee: Honeywell Inc.Inventors: Brad L.
