The lamp module having a lamp module form factor that is configured to be inserted into the lamp receptacle such that the lamp circuit contact member engages the contact element to thereby establish electrical connectivity between the lamp light module and the at least one terminal member, the lamp module also being removable from the lamp receptacle to thereby disengage the circuit contact member from the contact element.

A light switch assembly to replace an existing light switch, which generally includes a mounting bracket attached to an electrical box. The assembly slides into the mounting bracket and is locked into place with the mounting bracket. A decorative light switch cover and custom artwork within the frame snaps and locks onto the outer perimeter of the mounting bracket to complete the assembly. The assembly provides for a battery back-up system for power failure situations to illuminate the white, light emitting diodes in the event of a loss of power. The assembly senses the loss of power and unlocks the switch assembly from attachment to the mounting bracket. Unsnapping the decorative cover exposes the switch assembly so it can be removed from the mounting bracket. The switch assembly then becomes a mobile, hand-held emergency flashlight. The battery back-up system also allows for communication with first responders.

A small-sized simple switch for circuit protection of the present invention is simple in structure and easy to operate, and can be readily switched for safety protection of circuits. An alloy plate of the present invention is highly resilient. When in overload, the alloy plate expands and becomes deformed due to the different thermal expansion coefficient and is deformed upward to become disengaged from a wire connecting pad with which it is originally in contact, causing the switch to be switched from the "ON" condition to the "OFF" condition. The alloy plate pushes a lever pivoted to the moving end of the alloy plate to move up such that the lever pushes one end of a pivoted reset button to move up. A user only has to depress the reset button and the switch will be again in the "ON" condition such that repeated ON/OFF conditions of the protection circuit can be effected. If there is no overload on the circuit, the switch of the present invention will be operated to be in "ON" or "OFF" condition as ordinary switches.

An improved radio frequency transparent utility meter cover for an automatic meter reading (AMR) system. The cover is manufactured from a strong and chemically inert polyolefin or polypropylene copolymer and includes a non-corroding lock to secure the cover to the meter box frame. The underside of the cover includes a plurality of ribs that lend strength and rigidity to the cover while increasing mounting points for meter unit interface devices.

An improved circuit breaker includes an inertial time delay mechanism that permits a self-powered trip unit to become fully operational before inputting into the trip unit a signal indicating a change in the state of the circuit breaker. The time delay mechanism includes an inertia member, a first spring, and a second spring, and is activated upon the rotation of a lay shaft of an operating mechanism of the circuit breaker. The first spring extends between the inertia member and a housing of the circuit breaker and biases the inertia member from an initial position toward a terminal position. The second spring extends between the lay shaft and the inertia member and biases the inertia member toward the initial position when the circuit breaker is in an OFF condition. The combined action of the first and second springs on the inertia member provides a time delay using a relatively small inertial mass.

A switching mechanism provides sequential switching of first and second circuit breakers to enable switching between a primary power supply and a backup power supply. The switching mechanism comprises a first actuator plate to operate a first circuit breaker connected to a primary power supply, a second actuator plate to operate a second circuit breaker connected to a secondary power supply, and an actuator. The first and second actuator plates are independently movable between on and off positions. The actuator is operatively connected to the first and second actuator plates so that the actuator moves the first actuator plate to an on position and the second actuator plate to an off position when the actuator is moved in a first direction, and moves the first actuator plate to an off position and the second actuator plate to an on position when the actuator is moved in a second direction. An override enables movement of the first and second actuator plates from the on position to the off position when the other actuator plate is in the off position. The switching mechanism can be installed in an existing distribution panel in a home of building.
