摘要： A limit switch device is placed at an intended stop position, without the need to move the actuator additionally from the position at which the on/off state is switched. A first movable portion (211) causes a first contact to slide on a second contact in a switch mechanism (103) included in a microswitch by applying a force (F′) via an actuator (102a) and a plunger (102b).

摘要： 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.

摘要： A limit switch has a housing, a plunger that is supported in the housing while being vertically movable, a switch main body disposed in and fixed to the housing by the plunger, an operation shaft having an upper end thereof exposed from a ceiling surface of the switch main body, a contact that is opened and closed by driving the upper end of the operation switch, and a displacement expanding mechanism arranged between the switch main body and the plunger. The displacement expanding mechanism has a pair of pivoting tongue pieces rotatably supported by a pair of support shafts arranged in parallel with each other. A free end of one of the pivoting tongue pieces is abutted on the upper end of the operation shaft. A free end of the other pivoting tongue piece is abutted on an upper surface of one of the pivoting tongue pieces.

摘要： The invention provides a manual operation button having a large operable area. A manual operation button is composed of a manual operation plane, a holder for assembling the manual operation plane and a stopper for fixing the holder to a casing. The casing has a mounting hole having substantially the same size and shape as the manual operation plane, so that when the manual operation plane is assembled to the mounting hole, the manual operation plane forms a substantially continuous flat plane with the casing. The holder includes a substantially L-shaped mounting portion for mounting to the casing, a flat plate-like mounting plane for mounting the manual operation plane, and a hinge portion connecting the mounting portion and the mounting plane. The whole width of the hinge portion is disposed within the outer projection plane of the manual operation plane.
