An assembly including: a disk spring; a plurality of normally closed contacts disposed in a plane below the disk spring; a plurality of normally open contacts disposed in a plane above the disk spring; a pivot ring supporting a lower surface of the disk spring; and an actuating pin having a shoulder in contact with an upper surface of the disk spring; where a movement of the actuating pin away from a header assembly snap deflects the disk spring to a first position to contact the plurality of normally open contacts, and a movement of the actuating pin towards the header assembly snap deflects the disk spring to a second position to contact the plurality of normally closed contacts.

A flexure includes a flexure body with an inner ring defining a main axis and an outer ring extending about the inner ring that is outboard of the inner ring with respect to the main axis. One or more flexure members having respective lengths that are greater than a radial offset distance defined between the inner ring and the outer ring connects the inner ring to the outer ring. A valve includes a valve member connected to a valve body by the flexure.

A control device configured for use in a load control system to control one or more electrical loads external to the control device may include a first switch member and a second switch member. The control device may include an actuation member having an upper portion and a lower portion. The actuation member may be configured to actuate the first switch member and the second switch member in response to tactile actuations of the upper portion and the lower portion. The actuation member may include first and second pivot arms that enable the actuation member to pivot about a pivot axis in response to the tactile actuations. The first pivot arm may define a notch. The control device may comprise a light pipe configured to conduct light emitted by a light source through the notch to a light indicator located on the bezel.

A key switch includes a movable part configured to be moved by a pressing operation, a support mechanism that movably supports the movable part, an electrical connector including multiple pairs of contacts of upper electrodes and lower electrodes, and a disc spring that is disposed between the movable part and the electrical connector and configured to be elastically deformed by movement of the movable part and to press the electrical connector. The multiple pairs of contacts are provided for one movable part. When the disc spring is deformed by the movement of the movable part, the disc spring is configured to simultaneously press the multiple pairs of contacts provided for the corresponding movable part.

An assembly including: a disk spring; a plurality of normally closed contacts disposed in a plane below the disk spring; a plurality of normally open contacts disposed in a plane above the disk spring; a pivot ring supporting a lower surface of the disk spring; and an actuating pin having a shoulder in contact with an upper surface of the disk spring; where a movement of the actuating pin away from a header assembly snap deflects the disk spring to a first position to contact the plurality of normally open contacts, and a movement of the actuating pin towards the header assembly snap deflects the disk spring to a second position to contact the plurality of normally closed contacts.

A push switch includes a case having a recess with an open upper portion and a fixed contact inside the recess, a dome shaped movable contact member formed of a metal plate and accommodated inside the recess of the case, and an operation member configured to press the movable contact member, to cause an inversion operation of the movable contact member. The movable contact member has a sidecut shape having both sides of a circular shape forming a pair of linear portions in a top view, and a sidecut ratio represented by (B/A)100 within a range of 40% to 70%, where A denotes a diameter of the circular shape, and B denotes a distance between the pair of linear portions.
