Both Ends Of Blade Are Freely Floating Patents (Class 200/452)
  • Patent number: 9484166
    Abstract: A double-throw switch comprises: a housing; a push button that is mounted for movement with respect to the housing; a first stationary terminal; a second stationary terminal; a moveable terminal that, when in contact with the first stationary terminal, closes a first circuit, and when in contact with the second stationary terminal, closes a second circuit; a first set of one or more positive stops that engage the first stationary terminal; and a second set of one or more positive stops that engage the second stationary terminal. The first set of one or more positive stops applies pressure to and maintains a predetermined position of the first stationary terminal. The second set of one or more positive stops applies pressure to and maintains a predetermined position of the second stationary terminal.

  • Patent number: 9478372
    Abstract: A normally-open switch comprises: a housing; a push button that is mounted for movement with respect to the housing; a stationary terminal; a moveable terminal that, when in contact with the stationary terminal, completes a circuit; and one or more positive stops that engage the stationary terminal. When a force is applied to the push button, the moveable terminal makes contact with the stationary terminal, thus closing the circuit. When the force is removed, the moveable terminal breaks contact with the stationary terminal, thus opening the circuit. The one or more positive stops apply pressure to and maintain a predetermined position of the stationary terminal, but do not interfere with or impede the moveable terminal.

  • Patent number: 8459812
    Abstract: In one embodiment, a system may include an electrical device having an indicator light source, an actuator having a window, a viewing piece arranged to be visible through the window, and a light guide arranged to guide light from the light source to the viewing piece. The viewing piece may have a receiving portion arranged to receive light from the light guide, and the width of the receiving portion may be substantially larger than the width of the light guide. In another embodiment, a system may include an electrical device having a first support member, and an actuator having a second support member. The actuator may be adapted to move along a path of motion from a retracted position to an extended position, and the first and second support members may be adapted to support the actuator in the extended position with forces that are substantially balanced along the path of motion.

  • Patent number: 5808248
    Abstract: A fixed terminal having a fixed contact and an L-shaped moving member terminal are mounted through oblong openings of a bottom plate of a switch case at each one end. A moving switch-plate having a moving contact at one end part is suspended on the other end part of the L-shaped moving member terminal with a change-over member and a U-shaped leaf spring so that the longitudinal direction of the moving switch-plate is substantially parallel to the bottom plate of the switch case, and that the other end of the moving switch-plate is moved by a slide member to operate the switch.

  • Patent number: 5566819
    Abstract: A resilient bridge of a snap-action switch is normally held in an unactuated position by virtue of one end portion of the bridge bearing against a lobe formed integrally with a manually actuatable and linearly movable plunger. When the plunger is manually depressed toward an actuated position against the bias of a return spring, the lobe moves away from the end portion of the bridge. As an incident thereto, the bridge changes the state of the switch by automatically snapping over center along a path extending transversely of the path followed by the plunger.

  • Patent number: 5082997
    Abstract: Switch of the tilting blade type wherein the spring blade (35) provides for the tension of the moving blade (38) and the return of the pusher (39); under the action of the pusher(39) the spring blade (35) separates progressively from the inclined terminal (34); the inclination value is given for products in compliance with standard (DIN 41635, shape A); the closure system of the case comprises flanges which retain the cover; the shaft of the accessories is cast in a single operation.

  • Patent number: 4891481
    Abstract: An electrical snap-action type switch contact blade (80) is provided. Blade (80) has a base (6) and an electrical contact region (10) intermediate a pair of spaced-apart support legs (14) that extend angularly away from base (6) to respective free-ends. A tongue (12) extends arcuately away from region (10) in a direction opposite to support legs (14) and towards base (6) to a free-end (23). Free-end (23) of tongue (12) and the free-ends of support legs (14) respectively engage spaced-apart anchoring sites to secure blade (80) to the switch frame. Blade (80) can be actuated by application and removal of a Force (F) both against base (6) and for a prescribed distance (X) along support legs (14).
