A lever (24) mounted on a male housing (10) is formed with a connecting cam surface (29) capable of pressing a cam pin (41) of a female housing (40) while being kept out of contact with cam projections (23) in the process of rotating the lever (24) from an initial position to a connection position, and the lever (24) is formed with an escaping space (31). In the process of rotating the lever (24) from the initial position to the connection position in a state where the male housing (10) and the female housing (40) are separated and the moving plate (18) is at a protecting position, the cam projections (23) of the moving plate (18) are accommodated into the escaping space (31) while being kept out of contact with the connecting cam surface (29).

A power supply circuit breaker device (1) is configured to include: a fixed-side connector device (2) provided partway along a power supply circuit (D); a movable-side connector device (3) which engages/disengages with the fixed-side connector device (2) to turn ON/OFF the power supply circuit (D); and a rotary connection mechanism (4) for engagement/disengagement between the connector devices and turning ON/OFF the power supply circuit. The rotary connection mechanism (4) is configured such that, in the engagement/disengagement between the connector devices and the turning ON/OFF of the power supply circuit, the movable-side connector device (3) is made linearly movable along an engagement direction (P), and the movable-side connector device (3) is made rotatably movable in a direction (Q) around a rotation axis parallel to the engagement direction (P).

A lighting arrangement includes an assembly, a rail profile, and an adapter unit. The assembly is designed as a lighting module or lighting unit coupled to the assembly or accommodated by the assembly. The rail profile has a first region for accommodating the assembly and a second region, in which a conductor device for providing electrical energy is provided along the rail profile. The adapter unit is accommodated in the second region of the rail profile and is configured to be electrically coupled to the conductor device in the second region, to receive electrical energy from the conductor device and to provide electrical energy to the assembly for supplying the lighting module or the lighting unit. The adapter unit and the assembly are configured for electrical coupling so that the assembly displaces along a longitudinal direction of the rail profile relative to the adapter unit inserted into the second region.

A connector device produces a connection by means of Single Pair Ethernet (SPE). The connector device includes at least one connection element for an SPE connection, a light source for generating a light emission, and a light-guide element. The light source is set up to couple the generated light emission into the light-guide element, and the light-guide element is set up to couple an output-light distribution out in a coupling-out area.
