A system includes a mechanical switching device having a first moveable contact operatively connected to selectively contact a first static contact. A second moveable contact is operatively connected to selectively contact a second static contact that is electrically connected in parallel with the first static contact. The first and second moveable contacts are mechanically connected to each other to move between a closed circuit position and an open circuit position. The first moveable contact contacts the first static contact before the second moveable contact contacts the second static contact as the first and second moveable contacts move into the closed circuit position from the open circuit position. The first moveable contact disconnects from the first static contact after the second moveable contact disconnects from the second static contact as the first and second moveable contacts move from the closed circuit position into the open circuit position.

A switch assembly including a socket, a top cap, and an intermediate cart located in the socket. The intermediate cart is slidable with the socket. The top cap is in a spherical or pivot engagement with the intermediate cart. An activation force of the sliding movement is lower than an activation force of the spherical or pivot movement.

A push switch includes a movable contact member, a first fixed contact, and a second fixed contact. The push switch is in a first contact state in a first contact position where the movable contact member contacts the first fixed contact, and is in a second contact state in a second contact position where the movable contact member contacts the second fixed contact. The push switch is not switched to an on state in response to transitioning from an off state to the first contact state, and is switched to the on state in response to further transitioning to the second contact state, and the push switch is not switched from the on state to the off state in response to the second contact state being released, and is switched from the on state to the off state in response to the first contact state being further released.

A switch device includes: an operation unit including a first switch, a second switch, a first resistor, a second resistor, and a first terminal; and a control unit including a second terminal coupled to the first terminal. A series circuit of the first switch and the first resistor and a series circuit of the second switch and the second resistor are coupled between the first terminal and a ground. The control unit monitors a potential of the first terminal which changes in response to on/off of the first and second switches via the second terminal, and determines the operation state of each switch based on the potential. A contact of the first switch is configured of a contact in which a resistance value between contacts at the time of opening and closing changes more sharply as compared with a contact of the second switch.

Provided is a multi-position electrical switch. The multi-position switch includes an enclosure and a stem structured and arranged to move along a vertical axis within the enclosure. The stem provides a plurality of distinct horizontal protrusions as physical deactivators at different elevations along the vertical axis. A plurality of distinct electrical contacts are provided by a paired stationary element and a movable element for flexibly making and breaking electrical contact with the stationary element, the movable element biased for contact with the stationary element. Each distinct electrical contact is associated with at least one distinct horizontal protrusion. A spring disposing the stem in an initial position in which the plurality of distinct horizontal protrusions dispose all of the movable elements in broken contact. Depression of the stem along the vertical axis transitions the distinct horizontal protrusions away from the movable elements permitting contact with their paired stationary elements.

What is presented is a key module for a keyboard. The key module comprises a key tappet. The key module also comprises a module housing. The module housing is formed to movably accommodate the key tappet, in order to enable a translational actuation movement of the key tappet between a rest position and in an actuated position relative to the module housing. The key module further comprises a trigger element for triggering an actuation signal of the key module in response to the actuation movement. The trigger element is attached to the key tappet. The trigger element is a contactor for electrically shorting contact pads of a circuit substrate of the keyboard. The trigger element comprises more than two elastically deformable contact fingers for contacting the contact pads after different pre-travel paths in the course of the actuation movement.
