摘要: The emergency stop switch unit 2 as an operation switch unit includes a direct operation part 20A and an alternative operation part 20B. The direct operation part 20A has an emergency stop button 21 adapted to be directly operated. The alternative operation part 20B is adapted to be linked with the direct operation part 20A and alternatively operates the emergency stop button 21 in place of the direct operation part 20A. The alternative operation part 20B has a reception part 32 that detects a remote operation of the emergency stop button 21 and an electromagnetic solenoid 3 that actuates the emergency stop button 21 on the basis of the remote operation detected by the reception part 32.

摘要: An electrical switch including a frame, an operating shaft, and a bridge member movable in a depth direction relative to the frame by rotation of the operating shaft, wherein the depth direction is parallel with a rotation axis of the operating shaft, and wherein the operating shaft is adapted to exert a first opening force to the bridge member during an opening event. The electrical switch includes an anti-tilting member movable in a lateral direction relative to the frame by rotation of the operating shaft, the lateral direction being perpendicular to the depth direction, wherein the anti-tilting member is adapted to exert a second opening force to the bridge member during the opening event, the second opening force being parallel to the first opening force and spaced apart from it in the lateral direction.

摘要: A disconnector includes: a switch having: a first, fixed contact terminal of a first conductor, a second, fixed contact terminal of a second conductor, and a moveable bridge contact moveable between a first position and a second position; and an actuating mechanism having: a cam follower coupled to the moveable bridge contact and including a following surface, a cam having a cam surface, the cam surface engaging with the following surface, the cam being rotatable around an axial direction relative to the cam follower. At least one of the following surface and the cam surface includes an angled portion, the angled portion angled with respect to the axial direction such that rotation of the cam urges the cam follower in the axial direction, the cam follower moving the moveable bridge contact in the axial direction from the first position to the second position in response to the urging.

摘要: Disclosed herein are passive triggering mechanisms for activation of pyrotechnic features within electrical switching devices, such as contactor devices and fuse devices. The activation of the pyrotechnic features is configured to change the configuration of the internal components of the switching device and prevent current flow through the device. In some embodiments, the triggering mechanisms comprise features that respond to a magnetic field, such as a reed switch. In some embodiments, threshold strength of a magnetic field needed to trigger the passive triggering mechanism, which corresponds to a threshold level of current running through the switching devices indicating a dangerous overcurrent, can be adjusted based upon the distance between the passive triggering mechanism and a portion of the device such as a power terminal or feature connected to a power terminal.

摘要: 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.
