A switch device includes a switch body, a lead wire, a sealing member, and a holder. The switch body includes a switch housing and a first terminal protruding from the switch housing. The lead wire includes a tip portion fixed to the first terminal. The sealing member seals the first terminal and the tip portion. The holder covers the sealing member. The holder includes a connection portion disposed within the holder. The holder is fixed to the switch body by attaching the connection portion to the first terminal.

A contactor is proposed, which includes a stationary contact bracket having a main body and a plurality of terminals extending from the main body and configured to be electrically connected with wires, each of the plurality of terminals including a plate-shaped terminal body and a terminal hole penetrating through the terminal body; a junction box having a plurality of wiring holes and assembled to the stationary contact bracket, wherein each of the plurality of terminals is located in a corresponding wiring hole; wherein the surface of the junction box away from the stationary contact bracket is provided with a groove, and the groove is located between the plurality of terminals.

An electrical device such as, for example, a battery-powered electrical switch is disclosed. The battery-powered wireless switch includes one or more mechanisms arranged and configured to provide simplified access for servicing (e.g., replacing) the batteries located within the wireless switch. In one embodiment, the wireless switch is arranged and configured so that the batteries may be accessed by reconfiguring the wireless switch from a first closed position to a second opened position to access the batteries. Thus arranged, removal of the wireless switch from a wall-box or a surface of a wall is not required, the user may only need to remove the wall-plate in order to reconfigure the wireless switch. In one embodiment, at least a portion of the wireless switch is pivoted from the first position to the second position to provide access to the batteries.

A switch assembly includes a body including a plurality of pressable switches, and a controller configured to control a connected device according to inputs received from the plurality of pressable switches, wherein the body further includes a pin extending from a surface thereof; a switch cover including a recess formed in an interior surface for receiving the pin such that is pivotable about the pin, wherein the plurality of pressable switches are each disposed to be pressable by pivoting the switch cover about the pin.

The present disclosure relates to a LOTO for an MSD switch, a power battery comprising the LOTO, and a work machinery comprising the power battery. The MSD switch comprises a socket formed with a cavity. The LOTO comprises: a lock bracket which is disposed adjacent to the socket and is provided with a lock hole; a retainer which can be releasably locked with the lock bracket; and an insulating block which is mounted on the retainer. The retainer and the insulating block are configured such that when the retainer is locked to the lock bracket, the insulating block engages in the cavity. The LOTO of the present disclosure features simple structure and assembly, low cost and high versatility.
