A track adapter has a mounting seat, an electrical supply column, an adjustment conductive portion, and an adjustment knob, and a drive mechanism. As to the track adapter and the driving power supply with the track adapter and the track light, the lamp holder of the track lamp can wrap the whole track, which is neat and beautiful, and solve the problem of difficult phase adjustment of adaptor in the prior art at the same time. The phase adjustment knob is shrunk and put on the top of the adaptor, which solves the adjustment problem and adapts to more occasions, so that the structural design of the track lamp is more flexible.

A resettable switching apparatus, useful in a GFCI receptacle, has a housing with a face plate and at least one sense transformer core positioned to define a current flow direction through a center cavity that is parallel to the face plate. The GFCI receptacle further includes a space-efficient coaxial configuration in which a mechanical latching arrangement for resetting (i.e., closing) main switch contacts is disposed inside the trip solenoid. A movable carriage for the main contacts spans one end of the solenoid and has a latching portion in the solenoid that engages the inner end of a reset plunger in two sequential states (i.e., unlatched and latched). The mechanical latching arrangement comprises a cam surface coupled to a lifting plate, which is connected to the carriage of the GFCI receptacle. The cam surface is responsible for translating a downward movement to a translational movement to engage the carriage to the rest plunger.

An electrical connector system can comprise a first connector and a second connector. The first connector can include a first threaded coupling feature defining a first axis. The first connector can also include a first electrical contact with a first contact surface having an annular configuration centered on the first axis by a radius. The second connector can include a second threaded coupling feature defining a second axis. The second connector can also include a second electrical contact with a second contact surface offset from the second axis by the radius. The first and second threaded coupling features can be operable to engage one another to couple the first and second connectors to one another such that the first and second axes are aligned, thereby facilitating contact or separation of the first and second contact surfaces upon relative rotation of the first and second connectors.

An USB female socket, a button controller and a smart home. The USB socket may include a housing, a rubber core, and a set of terminals. The housing may define a cavity extending through a front end and a rear end of the housing. The set of terminals may include a first contact terminal and a plurality of second contact terminals. A front end of the first contact terminal may be located below a front end of a second contact terminal adjacent to the first contact terminal and thereby a variable gap may be formed between the front end of the first contact terminal and the front end of the adjacent second contact terminal.

Improvements are disclosed to lighting fixtures, support structures, interconnecting cabling, and other subjects. An improved method allows precise control of the beams of high power, long throw followspots by means of a steering mirror motorized in two axes. The beam is first directed upwards from the followspot by a first mirror to the steering mirror above. The range of elevations through which the beam can be steered is increased by displacing the steering mirror relative to the first mirror such that the portion of the beam between them is not vertical.

The present invention provides a power outlet with safety features having the form and size to fit standard electrical boxes. The present invention includes of one or more switched sockets which are generally switched on by movement from a first position to a second position. The described movement is prevented by one or more locks configured to be unlocked by complete insertion of a plug's power blades into the socket. In addition, optional blade locks may be provided to prevent removal of the plug once the movement from the first position to the second position has begun. The movements described herein are fixed, linear and rotary. An embodiment adapted for use with an extension cord socket is also presented.
