  • Patent number: 7884293
    Abstract: Such a control (10) firstly has a control housing (11) with a control rocker switch (21) which is mounted on the control housing in such a way that it can be rocked and at least two electrical wires in the interior of the housing, which protrude from the control housing (11) and are attached to an electrical drive of one lock. An electrical switch which in turn has a switch housing with a ductile snap disc (40), which interacts with at least two rest contacts as articulated contact when a switch actuator deforms the snap disc, is normally a part of this control. The rest contacts are connected to the wires in the control housing (11). In order to manufacture an economical and space-saving device, it is proposed that the control housing (11) is also used as the switch housing and that the control rocker switch (21) is also utilized as the switch actuator.

  • Publication number: 20080223698
    Abstract: A safety switch that includes a housing, a first switch, and a second switch. The switch has a two part rod that is axially moveable within the housing. The parts of the rod are co-operable with respect to one another and independently operable to activate one of the first and second switches. A biasing element is arranged to bias the rod parts into contact with a cam arrangement and arranged to bias the rod parts out of engagement with one of the respective switches. The cam arrangement is configured such that rotation of the cam arrangement will move the rod parts thereby activating the switches to allow the safety switch to conduct electricity.

  • Patent number: 7405374
    Abstract: A plunger switch comprises a switch body housing a first contact element, a second contact element and an elongate plunger. The first contact element is partially housed in the switch body and extends out for operative communication with a circuit. The second contact element is movable along a longitudinal axis of the switch body and is aligned to contact the first contact element through movement. The elongate plunger is movable along the longitudinal axis of the switch body, and is able to be completely recessed in the switch body. Movement of the plunger in a first direction facilitates contact between the first and second contact elements. The contact elements contact at contact portions. At least a pair of the contact portions may have ridged surfaces that are oriented so as to have intersecting points at contact and configured to perform oxidation cleanup. At least a pair of the contact portions may include silver nitride.

  • Patent number: 6803778
    Abstract: In a natural state of a probe (41), a plunger (61) is distanced from a rod (62) by a spring (63), the rod (62) is held in contact with a contact element (75) by a spring (74), so that the rod (62) is connected to a common conductor of a base plate via a barrel (55). On the other hand, when an end of a wire comes into contact with an end of the plunger (61) to push it toward the rod (62), the rod (62) is distanced from the contact element (75). To be electrically disconnected from the common conductor of the base plate. Thus, all the barrels (55) and contact elements (75) of a plurality of probes (41) can be held at a specified potential only by a wiring for the signal common conductor.

  • Patent number: 6621020
    Abstract: A breaking mechanism includes a latch receiver engaging a latch to allow a movable contact shoe to be closed, and a tripping device for rotationally driving the latch receiver to disengage the latch to open the movable contact shoe. An engaging surface of the latch engaging the latch receiver is formed as a projecting circular surface, whereas an engaging surface of the latch receiver engaging the projecting circular surface is formed as a recessed circular surface having a radius of curvature greater than that of the projecting circular surface. The center of the curvature of the recessed circular surface coincides with the axis of a support shaft supporting the latch receiver. The loads causing a tripping device to drive the latch receiver do not change even if the location of an engaging point is changed.

  • Patent number: 6396013
    Abstract: A moving member 20 for operating a contact mechanism is provided in a body case 12 in such a manner as to be movable in its projecting and retracting direction. A rubber-made waterproof cap 23 is provided on a front portion of the body case 12 in such a manner as to cover the moving member 20. When a door 31 is closed, the moving member 20 including the rubber cap 23 is pressed by the door 31 to turn off the contact, whereas when the door 31 is opened, the pressing force is canceled to turn on the contact. A distal wall portion of the rubber cap 23 is formed of a low-friction member to form a low-friction portion 23b. Consequently, contact surfaces of the rubber cap 23 and the door 31 are formed as low-friction surfaces, and contact surfaces of the rubber cap 23 and the moving member 20 are also formed as low-friction surfaces.
