Provided are a switch and an operation device which can expand the application range of switches using magnets, etc. A switch incorporated in an operation device includes a movable member with a first end side fixed and a second end side swinging when receiving a pressing, and a pressing member which presses the movable member, and further includes a permanent magnet (magnet) on the tip of the movable member, and a magnetic field detection part which detects a magnetic field. In response to an operation on the operation device, the pressing member of the switch presses the movable member downward. The magnetic field generated by the permanent magnet (magnet) and detected by the magnetic field detection part changes due to the pressing of the pressing member, and the switch outputs a signal based on the magnetic field detected by the magnetic field detection part.

An electrical control mechanism having a support. A central body that is movable in rotation about a central axis of rotation (AXROTC) carries a button that is movable in rotation relative to the central body about an offset axis of rotation (AXROTD) parallel to the central axis of rotation (AXROTC). First return means are interposed between the central body and the button, with second return means being interposed between the central body and the support. Two primary electric switches are interposed between the button and the central body on either side of a plane containing the central axis of rotation (AXROTC) and the offset axis of rotation (AXROTD). Two secondary electric switches are interposed between the support and the central body on either side of the plane.

A switch having a push panel, a rocker, and a rocker actuator that actuates the rocker each time the push panel is pushed by a user. The switch includes a conductive switch member, that is toggled by the rocker, to connect and disconnect a first terminal from a second terminal. The switch is constructed to help reduce dust and debris from entering into the wall switch, and the switch may provide a visual cue to indicate a current ON/OFF state of the switch.

Problem To be capable of specifying an operation of a knob. Solution A switch 1 includes an operation detecting portion 7 which detects an operation of the knob 5. The operation detecting portion 7 includes a movable member 6 which displaces in association with the operation of the knob 5, a through hole 62a which penetrates through a light shielding portion 62 of the movable member 6 in a thickness direction thereof, one optical source 15 which is provided on one side of the movable member 6 in the thickness direction, a light guiding path 9A which is provided on the other side of the movable member 6 in the thickness direction, and two light receiving elements 10A, 10A which are attached to the light guiding path 9A. The light guiding path 9A is arranged in a position of being capable of receiving light emitted from the optical source 15 through the through hole 62a when the movable member 6 is arranged in a predetermined position by the operation of the knob 5.

An operation lever of a work vehicle has the operation surface including: a connection portion; a front operation surface extending obliquely so that a height from a reference plane increases from the connection portion toward the forward side of the connection portion in a cross-sectional view including a front-rear directions and a front-side edge of the operation surface being defined as a front-side top portion; and a rear operation surface connected to the front operation surface, extending obliquely so that a height from the reference plane increases from the connection portion toward the backward side of the connection portion and a rear-side edge of the operation surface being defined as a rear-side top portion. A length in front-rear directions along the reference plane in the front operation surface is larger than a length in the front-rear directions along the reference plane in the rear operation surface.

Disclosed is a trim unit (200) for an electrical switch including a trim plate (210) that presents an opening (215) and a control member (220) that is received in the opening (215). In the trim unit, the trim plate (210) is mounted on a plane front face of a backplate (230) that includes a holder (241) for holding the control member (220) in the opening (215). An electrical switch includes an accessory mechanism and such a trim unit.
