An electric switch (1), in particular for manually operated electric tools or appliances with an electric motor, is switchable from outside by means of a plunger (13). A changeover device (40) is provided for setting the direction of rotation of the electric motor, which changeover device can be activated for example by a tappet (47) arranged on the outside. The switch (1) is constructed very compactly, which simplifies the sealing of a switch of this type.

The present teaching relates to a magnetic sensor residing in a housing. The magnetic sensor includes an input port and an output port, both extending from the housing, wherein the input port is to be connected to an external alternating current (AC) power supply. The magnetic sensor also includes an electric circuit which comprises an output control circuit coupled with the output port and configured to be at least responsive to a magnetic induction signal and the external AC power supply to control the magnetic sensor to operate in a state in which a load current flows through the output port. The magnetic induction signal is indicative of at least one characteristic of an external magnetic field detected by the electrical circuit and the operating frequency of the magnetic sensor is positively proportional to the frequency of the external AC power supply.

A single-phase brushless motor includes a stator, a rotor disposed within the stator, and sensors disposed around an outer periphery of the rotor. The stator includes a stator core made of a magnetic-conductive material, and a stator winding wound around the stator core. The rotor includes a rotary shaft and a pair of permanent magnetic poles. The stator core includes a pair of stator poles forming a receiving hole there between, and the rotor is disposed in the receiving hole. The inner circumferential surface of the receiving hole is located on a cylindrical surface which is coaxial with the rotary shaft and two locating slots which are symmetrical with respect to a center of the receiving hole are defined in the inner circumferential surface of the receiving hole, which can improve the distribution of magnetic flux, effectively reduce cogging torque, and increase operation efficiency.

An actuator drive, for blinds, roller shutters and the like, has a drive motor (11) and a centrifugal brake (9). A rotational disk (4) is coupled to a drive shaft (7) of the drive motor (11) via a shaft flange (5). Two centrifugal shoes (2) are smoothly guided in the rotational disk (4). In the unpowered state, brake shoes (8) of the centrifugal shoes (2) engage, frictionally or in a positive-locking way on an outer surface of a friction ring (3) fixed to the motor housing (14). Upon starting of the drive motor (11), the brake shoes (8) release the friction ring. The radial displacement of the brake shoes (8) is maintained until the drive motor (11) comes to a stop, wherein the brake shoes (8) are drawn radially inward by spring elements (6) and function again as a locking mechanism. The spring elements (6) are pretensioned such that the brake shoes (8) effect a sufficient retaining torque.

A sensor integrated circuit includes a rectifier, a power supply module, an output control circuit and a detecting circuit. The rectifier is configured to convert an external power supply into a first direct current power supply. The power supply module includes a voltage regulator configured to generate a second direct current power supply different from the first direct current power supply. The detecting circuit is powered by the second direct current power supply and configured to detect an inputted signal and correspondingly generate a control signal. The output control circuit is configured to control, in response to at least the control signal, the sensor integrated circuit to operate in at least one of a first state in which a current flows out from an output port and a second state in which a current flows in from the output port

A sealed electrical connection assembly joins an electrical component to a plug-in component. For liquid-tight sealing, the free, deformable ends of the conductor tracks of the electrical component and/or the contact elements of the plug-in component are provided with hydrophobic surfaces at least regionally, so that even after a plurality of plug contact operations have been performed, in the coupling position and, optionally, in the uncoupled position, the contact region is surrounded by hydrophobic surfaces.

A shut-off valve for integration into an intelligent gas meter for residential or industrial gas supply, has an inlet, an outlet and a valve seat having a lip seal. A shut-off body is longitudinally displaceable with respect to the valve by a motor driven transmission, using a nut-threaded-spindle drive, to engage with or disengage from, the seal to open or close the valve. The transmission of the valve remains largely unbiased in the closed state while maintaining the gas-tightness of the valve.
