Abstract: There are provided, together with two microswitches 20 accommodated in a cylindrical compartment 13, a manipulation member 2 which can freely swing about a pivot portion 2a in the directions of arrows A and B, a transmission member 3 which can freely move in reciprocating motion within a specific range between a transmitting position and a non-transmitting position located along a radial direction of an arc which is the trajectory of the swing motion of the manipulation member 2 in the directions of the arrows A and B, a contact member 4 which can freely move in reciprocating motion within a specific range between an exposed position and a retracted position in the directions of arrows E and F, a driven member 5 which can freely move in reciprocating motion in the directions of arrows G and H, and a restricting part 6 fixed at a position opposing the contact member 4.

Abstract: In a switch device, a support arm is retained by a conductor plate at one of its ends and by a center terminal at its other end The spring member, which made of an elastic round wire, is placed in a bent form between the conductor plate and the center terminal so as to movably support the conductor plate on the center terminal. The support arm and the spring member are retained by the conductor plate and the center terminal on arc-shaped surfaces.

Abstract: A compact snap switch that can be assembled mechanically and is equipped as a microswitch. The switch includes a housing for the microswitch and consists of two asymmetrically divided halves whose cut site runs along the edge of one of the large side surfaces. Thus a comparatively large assembly window and a favorable assembly direction are obtained due to the few undercuts of the components. In addition, due to the minor modifications of the machine-instrumented components, the switch can be easily modified for the different application formats. A movable contact lever with a moving contact is mounted so as to pivot in a knife-edge bearing. The free end of the contact lever has a wedge profile which with one of its two sides is exposed to a switching roller reloaded by a switching spring. Switching roller and switching spring are seated in a switching member which is movable along a straight path and abutted by a restoring towards an idle position.

Abstract: A see-saw switch capable of closing the contacts at a high initial contact pressure. The switch includes a housing provided with a fixed contact, and a lever provided with a movable contact at one longitudinal end thereof. The lever is pivotally supported to the housing for pivotal movement about a pivot axis between a contact closing position and a contact opening position. A plunger is slidably supported to the housing for linear movement along an axial direction of the plunger, and has an actuator which is held in slidable contact with said lever for translating the linear movement of the plunger into the pivotal movement of the lever so that, when the plunger moves in a forward direction, the actuator causes the lever to pivot about the pivot axis into the closed position.
