11538642 · 2022-12-27 · ·

A switching device is for a low-voltage electric circuit having a plurality of conductors. In an embodiment, the switching device includes a housing having connection contacts arranged on the housing for connection of conductors of the low-voltage electric circuit; and a mechanical unit situated in the housing having an isolating function and an OFF or IN position, the mechanical unit including isolating contacts for galvanically interrupting the conductors of the low-voltage electric circuit. An electronic unit is provided which is connected to the mechanical unit in series on the current flow side; an auxiliary switch connected to the mechanical unit is provided and is connected in turn to the electronic unit; and the auxiliary switch and the electronic unit are designed in such a way that the electronic unit is highly resistive during an opening process of the mechanical unit.

Systems and methods for relay contact assembly reduction

Systems and methods for contact erosion mitigation are provided. To perform contact erosion mitigation, an order of opening/closing poles and/or contact relays of particular poles is altered, resulting in a sharing of potential arcing conditions amongst the poles/contact relays of these poles.

COVER TYPE TOUCH SWITCH STRUCTURE

A cover type touch switch structure includes: a seat housing embedded in a seat of a vehicle so as to be fastened to a seat frame; a switch housing disposed in the seat housing and including an outer surface which is coupled to the seat housing via a hook; a light-emitting unit which is disposed in the switch housing and stacked on the seat frame; and a knob unit which has a portion disposed in the switch housing and is stacked on the light-emitting unit.

Operation device

An operation device includes a movable member that is movable within a predetermined range, and a restriction member that is disposed in a state of being movable in a movable direction of the movable member, that restricts the movable range of the movable member by coming into contact with a contact surface of the movable member in the movable direction, and that can be switched between a state of being in contact with a first range of the contact surface and restricting the movable range of the movable member and a state of being in contact with a second range, the second range being different from the first range, of the contact surface and restricting the movable range of the movable member.

STATUS INDICATOR FOR SWITCHGEAR

A switchgear assembly includes an indicator assembly to indicate whether a movable contact is in an open or a closed position. The indicator assembly includes an indicator body having first and second sections. The indicator body is rotatable to display the first section in the open position and the second section in the closed position. The indicator assembly also includes a drive gear having a first helical spline and coupled to an actuator of the switchgear assembly such that operation of the actuator moves the drive gear, and an elongated driven gear having a second helical spline extending along a length of the driven gear and engaged with the first helical spline of the drive gear such that movement of the drive gear rotates the driven gear. The driven gear is coupled to the indicator body such that rotation of the driven gear causes rotation of the indicator body.
