An ignition switch includes a rotor into which a vehicle key can be inserted, a switch body rotationally accommodating the rotor, and a key interlock mechanism integrally coupled to the switch body. The key interlock mechanism prevents removal of the vehicle key when the vehicle is traveling.

A motor vehicle ignition switch has a first and a second electrical circuit for detecting the angular position of a key in an ignition lock, with a rotor that is rotatable about a rotation axis so as to be able to selectively take an off position, a starting position, a running position, an on position and an intermediate position, distinct from each other; the second circuit is independent of the first circuit and defines a resistive divider; the first circuit has a first, a second and a third conductive laminas, electrically isolated from each other; the first circuit has two contacts, one of which is arranged on the third lamina in the running position and in the starting position and on the first lamina in the intermediate position.

A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an arrangement of latching jaws (14). Each latching jaw (14) is spring-mounted by means of a spring unit (15). The latching jaws (14) are concentrically arranged and each face one another with a first free end and delimit an insertion opening (A). The latching jaws (14) are held in latched position by the spring forces generated by the spring units (15). The latching jaws (14) can be displaced against the spring forces of the spring unit (15), which serves to enlarge the insertion opening (A).

A key holder designed for use with manual key switches affixes a key onto a control box. The key holder includes a rotor housing, a key rotor, and a threaded opening. The key is mounted into the key rotor before being inserted into the control box. Further, the key rotor is rotatably mounted into the rotor housing via the threaded opening. The key rotor includes an interior face, an exterior face, a threaded body, and a key slot. The interior face and exterior face are positioned opposite each other about the threaded body. The key slot traverses through the threaded body. To connect the key rotor to the rotor housing, the threaded body is screwed into the threaded opening. This transforms the rotational motion into the linear motion of the key rotor, which along with the locking feature of the manual key switch, prevents the key from rotating.

A dry-type transformer with an elliptical iron core includes a transformer housing, a heat dissipation mechanism, an elliptical iron core, a coil, a clamping mechanism and an upper cover. The heat dissipation mechanism is arranged in a horizontal direction and fixedly assembled with the transformer housing. One end, away from the transformer housing, of the heat dissipation mechanism is in contact with ground. The elliptical iron core is arranged in a vertical direction inside the transformer housing. The coil is wound on the elliptical iron core. The clamping mechanism is sheathed on one side, away from the elliptical iron core, of the coil. The upper cover is arranged at a top end of the transformer housing, and the upper cover is fixedly assembled with the transformer housing via a bolt structure.

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).
