Plug connections and in particular plug connections for use in an industrial environment are presented. An attachment housing arrangement has an attachment housing for accommodating a hood of a plug connector with plug contacts and a mechanical locking arrangement for mechanically locking the hood on the attachment housing. Also presented is a method for unlocking a mechanical locking of a hood of a plug connector with plug contacts on an attachment housing of an attachment housing arrangement. The attachment housing arrangement is provided with a fixing arrangement for fixing the mechanical locking arrangement at least in a locking state, and with a control unit for controlling the fixing arrangement, the control unit being configured to control the fixing arrangement so as to release a fixing of the locking arrangement only when the plug contacts are free of current and free of voltage within predefined tolerances.

A switch seat body structure includes a main body for assembling with a switch component. The main body is composed of a metal head section in the form of a thin sheet structure and a nonmetal belly section. The main body is defined with an axis. The metal head section has a first wall normal to or inclined from the axis and a second wall connected with the first wall and parallel to or inclined from the axis. The first and second walls together define a space. The nonmetal belly section fills the space to connect with entire sections of the first and second walls as an integrated body. The switch seat body assembling structure improves the problems that the processing and manufacturing processes are time-consuming and troublesome and the material cost is higher.

A stackable electrical contact block includes a housing, the housing having a top and bottom side and accommodating a first and second electrical terminal, an actuation pusher adapted to move from a resting position to an actuated position to break the contact between the first and second terminals, the actuation pusher having a head protruding from the top side, a clearance below the actuation pusher, and a return spring biasing the actuation pusher towards its resting position, a bottom end of the return spring extending into the clearance. The housing's bottom side is a connection interface with an entrance providing access to the clearance. A central part of the clearance is taken up by the bottom end of the return spring, and a peripheral part is a space for receiving the actuation head of a component connected to the contact block via the connection interface.

An acoustic output device includes a base case whose internal space is formed as an arrangement space and in which an insertion hole communicating with the internal space is formed, a cover that covers at least a part of the base case, an elastically deformable waterproof sheet including a flat surface portion joined to the base case and a bag-shaped pocket portion inserted into the insertion hole, a push button including an operating portion to be pressed and operated and a working portion inserted into the pocket portion, a substrate that is arranged in the arrangement space, and a switch that is arranged on the substrate and operated by the working portion via the pocket portion.
