Patent number: 6271489Abstract: A pressure switch device and method of forming the device is disclosed. The switch has a hinge terminal having a fixed end of a blade apparatus pivotally attached thereto, a jaw terminal adapted to receive a free end of the blade apparatus at a receiving portion, the blade apparatus having two blades fastened together and a spacer between the blades. Pairs of cams at either end of the blades rotate to engage protrusions in order to create a pressure lock. The pressure is enhanced by a spring washer. A connecting link attached one of each pair of cams, a drive link attached to the blades and connecting link, and a drive shaft cooperate to open and close the switch such that the switch may be first placed in a closed position, and then locked by further rotation of the drive shaft as the cam protrusions engage. The drive shaft is spring loaded to create torsional force which must be overcome to rotate the drive shaft in either direction.Type: GrantFiled: December 31, 1999Date of Patent: August 7, 2001Assignee: Square D CompanyInventors: Edward I.

Patent number: 5722534Abstract: A power disconnect switch having a generally parallelepiped base with first and second electrical conductors mounted thereon. A switch piece pivots on one of the electrical conductors to connect to the other electrical conductor. The switch piece has an insulated handle, and a projection extends from the handle. The projection has a shape which allows it to fit snugly into a holder tool, and this allows an operator to open the switch without danger of electrocution. An angled insulating plate which fits next to the parallelepiped base has a side portion which insulates the switch from adjacent switches, and a bottom portion which insulates screws in the parallelepiped base from a metal panel, shelf, or box, on which the switch may be mounted.Type: GrantFiled: July 31, 1996Date of Patent: March 3, 1998Inventor: Jere Wright

Patent number: 5486669Abstract: A lever type switching assembly having a pair of generally U-shaped spring blade contact members disposed in oppositely spaced-parallel arrangement for alternate actuation by a common paddle lever frictionally contacting the contact members for effecting switching upon user movement of the lever in a clockwise direction. Each contact blade member has one end pivoted on a center contact for rocking motion to cause the U-shaped region and the opposite end of the blade member to make and break contact with side-contacts on opposite sides of the center contact. Overtravel of the paddle in one direction after actuation causes the contact blade member to break from the side contact and make contact with an auxiliary contact. A spring biased plunger on the paddle lever engages a detent surface on the base to give a tactiley discernible indication.Type: GrantFiled: October 21, 1994Date of Patent: January 23, 1996Assignee: Eaton CorporationInventor: Thomas J.

Patent number: 5073686Abstract: A bar providing a switching member is pivotally connected to a terminal supported within an insulating housing. In normal operating position the knife switch is closed to two switch contacts which allow connection of power from one of the contacts to two types of circuits, such as propulsion and the auxiliary circuits of a railway car. The insulating housing may be provided with a cover which is closed when the switch is in normal closed circuit operating position. To change the position of the switch, the cover must be opened. The bar may be pivoted somewhat less than 180.degree. to engage a single contact which connects the power to one of the circuits, but not the other, for example, only to the auxiliary circuit of a railway car. The knife switch is prevented from moving 180.degree. by an end wall of the housing. But in that position it closes to one contact so that it may be viewed as being closed to power the auxiliary circuit.Type: GrantFiled: September 21, 1990Date of Patent: December 17, 1991Assignee: Bombardier CorporationInventor: Claude D.
