Quick-mount electrical components including a body and a receiver. The body includes a first protrusion, a connecting portion distal the first protrusion, the connecting portion containing a first set of one or more electrical contacts, and a second protrusion proximate the connecting portion. The receiver includes a guide, a wire trap proximate the guide, a receiving portion distal the guide, the receiving portion containing a second set of one or more electrical contacts, and a retainer proximate the receiving portion. The first protrusion has one or more recesses that match corresponding alignment elements on the guide such that the body is keyed to only fit certain receivers, depending upon the electrical characteristics of devices wired to the receiver.

An electrical connector for an electrical connection is disclosed, comprising a female receptacle to connect to either a male shorting cap or a male plug. The male plug and female receptacle can be fastened to a standard knockout in a light fixture. The male plug and female receptacle have alignment means such that they can only fit together one way, and once together are positively connected by means of a twist-lock ring. The male plug is connected to the female receptacle by aligning the two fins to the two corresponding grooves, and pushing inward such that the protrusions of the female receptacle pass through the indentations in the ring of the male plug. The twist-lock ring is turned and the nubs on the protrusions engage the notches of the female receptacle, creating a removable twist-lock ring.

A waste water purification system with complementary interlocking germicidal lamp and socket construction to prevent unintentional disconnection of the lamps. This is attained by providing the germicidal lamps with locking contact pins arranged to be latched and locked to its complementary socket by providing the socket with keyhole slots for receiving the contact pins and associated spring biased displaceable contacts to maintain electric contact between the lamp and its socket in the assembled position. In one form of the invention, the contact pins of the lamps are longitudinally offset and spaced apart to prohibit arcing between the contact pins of the respective lamp electrodes. Other embodiments of the disclosure effect the interlocking of the lamp to its socket by complementary latching members formed on the end of the lamp and its corresponding socket.

The electric load comprises a carrier plate (1) of a synthetic resin material, at a first side (2) of which, synthetic resin projections (30) are present, which serve as a means for coupling the electric load to a holder. The projections (30) have a leg (31) with a disc, which faces away from the plate (1), and a channel (33) accommodating a current conductor (5) of a load element (4), which is present at a first side (3) of the plate (1). The disc has a circumferential side face (35), which is covered with an electric conductor (20) as a contact, to which a respective current conductor (5) is connected. The electric load, for example a fluorescent lamp switch, is of a simple construction that can be manufactured at low costs.

An electrical device having a base from which extend two parallel connector pins each having a small-diameter shank and a large-diameter head is fittable with a socket having a housing formed with a transverse wall having front and back faces and having between the faces a predetermined thickness substantially less than a distance between an end face of the device and the heads. The wall is formed with a pair of throughgoing slots each having a wide end through which a respective one of the heads can pass and an opposite narrow end so that the device can be fitted to the housing by passing the heads of the pins through the wide ends until the device end face engages the wall front face followed by turning of the device to displace the heads toward the narrow ends of the respective slots. A respective ramp at each of slots adjacent the respective narrow end is engageable with an underside of the respective head and is angled such that, on movement of the respective pin toward the respective narrow end, the respective head is cammed backward away from the wall back face and the device end face is pressed against the wall front face. Respective electrical contacts on the housing at the slots engage the heads of the respective pins when same are at the narrow slot ends.

A fluorescent-lamp socket assembly has a socket, a standard base, and a starter base. The socket has a nonconductive housing having an open end and a pair of conductors in the housing engageable with contact pins of a lamp fitted to the housing and exposed in the open housing end. The standard base is shaped to fit complementarily into and close the open housing end and is formed with throughgoing holes through which wires can be engaged with the conductors. The starter base has a one-piece nonconductive housing having a plug end shaped to fit complementarily into and close the open housing end and an opposite end adapted to hold a starter and a conductor inside the starter-base housing for connecting a starter in the opposite end with one of the conductors in the socket.
