Abstract: A screw, in particular for housings, has an elongated section provided at least in parts with a thread, and a screw head. A cone-shape section may be arranged between the screw head and the elongated section, wherein the point of the conical section connects to one end of the elongated section, and the underside of the screw head may be arranged opposite the base surface of the conical section, and a groove for accommodating a seal may be provided between the underside of the screw head and the base surface of the conical section.

Abstract: A signaling apparatus for command and/or indicating devices includes a base unit having at least two light sources which each generate light and are arranged on the base unit at a spacing from one another, and at least two light modules which are stacked along a main axis of the signaling apparatus and are operatively connected to the light sources such that light generated by the light sources is coupled into the light modules in a beam direction parallel to the main axis, the light modules each having a reflection region for reflecting at least in part the light coupled into the light modules in a signaling direction. A particular reflection region occupies only a portion of the light module in a peripheral direction of the corresponding light module perpendicular to the main axis of the signaling apparatus, which portion is smaller than a total periphery of the light module.

Abstract: An operating or command element has a key plate having a substantially flat or slightly curved basic form and having a plurality of surface elevations, which are formed on the basic form and which can be tactilely sensed using a fingertip so that the position of the fingertip on the key plate can be sensed. Both in a horizontal and in a vertical installation position of the operating or command element, the key plate can be free of recesses in which liquids can accumulate. Other installation angles are also possible, for example in the case of installation in an inclined console housing.

Abstract: A circuit breaker baying a switch housing and at least one contact for tapping a voltage on a primary conductor.

Abstract: A power-switch having a switch housing and an electronic module, at least one contact being provided to tap a voltage at a primary conductor, and an adapter being provided to reduce the tapped voltage of said primary conductor.

Abstract: Arrangement for establishing and/or breaking a connection between a plug and a complementary mating plug, wherein a lever which can be pivoted about an axis is arranged on the plug. The connection between the plug and the mating plug can be broken when the lever is pivoted into a disconnection position and/or can be established when the lever is pivoted into a connection position. The plug is, in particular, a switch module, for example a tripping module for a mating plug which is in the form of a circuit breaker.

Abstract: A solar module includes a plurality of serially connected photovoltaic solar cells and current connections configured to provide solar current generated by the photovoltaic solar cells and configured for connecting the solar module to at least one additional solar module. A mechanical switching contact is connected in parallel with the serially connected solar cells and a pressure actuator is connected to the switching contact. The pressure actuator is configured so as to open the switching contact against the action of a spring element in response to a control pressure above a predetermined threshold and so as to allow closure of the switching contact by action of the spring element in response to a control pressure below the predetermined threshold. The pressure actuator is connected to a control connection for coupling to a control pressure line.

Abstract: A switching arrangement includes a plug and a complementary mating plug for establishing and separating a connection between the plug and the mating plug. The plug includes a locking bolt disposed rotationally about an axis. The locking bolt includes a thread and the mating plug includes a mating thread. The plug is lockable to the mating plug by driving in the thread of the locking bolt into the mating thread. The switching device is configured to be moved to a connected position by driving in the thread of the locking bolt into the mating thread, and thereby providing a movement of the plug relative to the mating plug, and is configured to be moved to a disconnected position by driving out the thread of the locking bolt from the mating thread, thereby providing the movement of the plug relative to the mating plug.

Abstract: A self-recovering current-limiting device with a liquid metal includes two T-shaped electrodes for connection to an electric circuit to be protected. Each of the electrodes are made of a solid metal. Several compressor cavities which are partially filled with the liquid metal are situated one behind the other between the electrodes. The compressor cavities are formed by pressure-proof insulating bodies and by insulating intermediate walls which are provided with connecting channels and which are held by the insulating bodies. The insulating bodies and the intermediate walls form a uniform upper and lower half shell with opposite-lying joining surfaces. The half shells are connected in a sealed manner along joining surfaces in the area of a common middle plane of the connecting channels. Up to half of each of the electrodes is accommodated in corresponding recesses of the half shells, the electrodes extending with their respective middle limb out of the half shells.
