Abstract: A plug and socket assembly (100) includes a socket (110) with a receptacle portion (113) configured to receive an electrical plug (105) and an interlock mechanism (130) configured to retain the electrical plug (105) in the receptacle portion (113) when the receptacle portion (113) is rotated about a first axis to a first position. The assembly (100) includes an electrical switch (140) including an actuator (145) operable to energize and de-energize the socket (110). The assembly (100) includes a transfer mechanism (150) having a first mechanical component (310, 410) operable to transfer the rotation of the receptacle portion (113) into motion relative to the first axis that operates the actuator (145). Methods of operating a plug and socket assembly (100) are also provided.

Abstract: The invention relates to a protective collar for at least partially receiving an actuating element which extends through a housing of a control unit and projects beyond an outer side of the housing. The protective collar has a base with a through-opening and a first circumferential collar radially spaced from the through-opening and extending from an upper surface of the base in a first direction. The first collar has at least two cut-outs such that the first collar forms at least two wings, wherein at least one of the wings has at least one predetermined breaking point extending in the circumferential direction.

Abstract: The invention relates to a pressure relief device (1) for a housing (2) which is protected against explosions, in particular is compression-proof and has a wall connecting piece (3) which can be at least partially inserted into a housing opening (4) of a housing wall (6) by its insertion connecting piece section (5), which can be in particular detachably fixed from an inner side of the housing and rests from the outside on an opening edge (8) of the housing opening (4) in its inserted and fixed position with a radially outwardly projecting support flange (7), wherein the insertion connecting piece section (5) furthermore comprises a projecting connecting piece section (9) which is opposite the insertion connecting piece section relative to the support flange (7) and comprises a longitudinal conduit (10) running through the wall connecting piece (3) into which conduit a flame-blocking body (11) is replaceably inserted, wherein a pressure nut (13) which loads the flame blocking body (11) with pressure in its in

Abstract: The invention relates to an electrical distribution system (1), having a housing (3), in which fastening rails (13) are provided, which provide fastening points (15), which are arranged in lines, for the fastening of electrical components (17). Additionally, one or more, in particular explosion-protected, line-shaped heating elements (19) are provided in the housing (3), which heating elements each comprise a radiator body (23). The one or more heating elements (19) are each arranged below an associated group of fastening points (15), where electric current can be applied to the heating elements in order to heat electrical components (17) fastened at the associated fastening points (15).
