The present invention relates to an adapter (1) for connecting a light to a track having mains phases and comprising a housing (2), at least one spring-loaded connector (6.1) linked to the housing (2), and a cover (4) partially covering the housing (2) and having at least one opening (8.1). The cover (4) is displaceable so as to be placed selectively in one of: a position in which the at least one spring-loaded connector (6.1) extends at least partially through the at least one opening (8.1), a position in which the cover (4) covers the at least one spring-loaded connector (6.1).

A scalable universal power supply and/or power converter provides independent voltage, frequency, phase, and current control through a common power bus connected to a plurality of electrical conversion modules which can provide voltage, frequency, phase, and current control. According to one embodiment, a power supply and/or power converter includes a power bus; a plurality of terminals for input and/or output of electricity; a plurality of electrical conversion modules connected in parallel to the bus for transferring or converting electricity; a switch matrix, formed of a plurality of switches arranged in an array, connecting to the plurality of electrical conversion modules and the plurality of terminals; and a controller configured to select and operate one or more electrical conversion modules and one or more switches of the switch matrix to selectively provide and/or receive electricity to the one or more terminals.

An electrical receptacle including a body having a plurality of electrical connections, a device face connected to the body, and wherein the device face is movable with respect to the body from an electrically inactive position to an electrically active position. The electrical receptacle may further include at least one pair of electrical contacts which are in electrical continuity when the electrical receptacle is in an electrically active position.

[Object] To provide a common plug for AC/DC which can easily prevent erroneous insertion into a plug receptacle.

[Solution] Provided is a common plug for AC/DC including at least one pair of connection terminals. At least one connection terminal of the at least one pair of connection terminals is able to rotate around an axis of an insertion direction into a socket so as to have a first state in a case where the connection terminal is inserted into a socket for supplying AC power and a second state in a case where the connection terminal is inserted into a socket for supplying DC power, the second state being different from the first state.

An internally switched female receptacle or connector for use with IEC 60309-2 configuration plugs and the like. Various plug-latching and plug-actuated safety interlock arrangements coordinate strictly axial plug movement relative to the receptacle with the closing and opening of sleeve contacts and terminal pressure contacts. A continuous ground feature ensures grounding of the primary electrical circuit throughout plug insertion and withdrawal. An optional low-current lighting control circuit powers an LED status indicator. A modular clocking design enables variable angular positioning of the terminals during manufacture.

A PDA terminal is provided. The PDA terminal includes: a main body; a processor disposed in the main body; a memory accessible by the processor; and a display unit disposed on a front surface of the main body to display information processed by the processor. A rear cover detachable from the main body is disposed on a rear surface of the main body. After the rear cover is removed, a gun handle is usable in a state of being connected to a coupling part formed under the rear cover. Since the gun handle with a switch is usable in a state of being connected to the main body of the PDA terminal, the operation of the PDA operation can be more conveniently used in an industrial site or the like.
