A switching apparatus for electric power distribution grids including: a withdrawable first switching unit having one or more first electric poles; a withdrawable second switching unit having one or more second electric poles and electrically connected ins series with said first switching unit; a controller implementing control strategies directed to increase the safety of the withdrawal manoeuvres of said first and second switching units.

A switching apparatus for electric power distribution grids including: a withdrawable first switching unit having one or more first electric poles; a withdrawable second switching unit having one or more second electric poles and electrically connected ins series with said first switching unit; wherein said second switching unit includes an emergency control arrangement activatable by a user to make said second switching unit to carry out an opening manoeuvre.

A power circuit interrupting device including a first housing including a pair of fixed electrodes and a fuse having terminals at both ends thereof, and a second housing including a moveable electrode, the moveable electrode interrupting electrical connection between the fixed electrodes when the second housing is uncoupled from the first housing, and establishing the electrical connection between the fixed electrodes when the second housing is coupled with the first housing. The first housing has an opening provided for carrying out a continuity test for the fuse. The opening is always covered with the second housing in a condition that continuity of a circuit is allowed. The power circuit interrupting device serves to facilitate the continuity test for the fuse built therein and comply with such a maintenance procedure that the continuity test should be carried out after interrupting continuity of the power circuit.

A shift assembly structure of switch device includes a connection seat formed with an assembling hole for rotatably connecting with a main body. A latch section is disposed on the bottom of the connection seat for latching and assembling with a wire-connection module. The connection seat has an arm protruding from the connection seat and an (elastic) restriction section formed on the arm. A shift body is assembled in the connection seat. The shift body is formed with a ridge section and a push/press section. When the shift body is moved from a first position to a second position, the ridge section is permitted to directly pass through the restriction section into a locked state. After the push/press section pushes the restriction section, the main body is unlocked from the connection seat, whereby the assembly of the main body and the connection seat is controllable.

A switch device includes at least one switch module and at least one welding protective plate. The switch module includes an enclosure for receiving a plurality of control terminals and a driving member therein. The control terminals respectively have an end projected from an end or a rear side of the enclosure. The driving member is controllable to change an electrically connected or disconnected state between the control terminals. The welding protective plate is provided on the enclosure at the end from where the control terminals are projected. The projected control terminals further extend through the welding protective plate to be welded to a circuit board. The welding protective plate can withstand a high temperature and is located between the switch module and the circuit board to form a thermal insulation and protection mechanism, protecting the switch module from external deformation and inner damage by the high temperature during welding.

A remote control device may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may include a control unit and a base that may be configured to be mounted over a paddle actuator of an installed mechanical switch. The base may include a frame, a biasing member, and/or a ribbon portion. The frame may be configured to secure the remote control device thereto. The frame may define a rear surface that is configured to abut a bezel of the mechanical switch. The biasing member may be configured to engage a rear surface of a faceplate of the mechanical switch. The ribbon portion may be configured to attach the biasing member to the frame. The ribbon portion may be configured to extend through a gap between the bezel and the faceplate.
