Abstract: The invention is relative to a junction box auxiliary securing structure comprises an auxiliary securing plate mounted in the junction box, and a switch base mounted securely on the auxiliary securing plate. The auxiliary securing plate, from outside to inside, oppositely defines long slots, short slots, and a central hole formed at a center thereof. The four corners of the central hole have securing tongues slantly extending therefrom and toward a center of the auxiliary securing plate. Two sides of the switch base have outer fixing holes and inner fixing holes, respectively. The outer fixing holes are corresponding to the long slots of the auxiliary securing plate, the inner fixing holes are corresponding to the short slots of the auxiliary securing plate. With such, the drawback of being incapable of mounting the switch base due to rustiness of the junction box is therefore avoided.

Abstract: In a switching circuit, at least two bus bars are fixed with an insulator interposed therebetween and secured to a substrate of the switching circuit. Being combined with the bus bars, the insulator serves not only to insulate those bus bars but also to enhance the bending rigidity and bending strength of the switching circuit. As current flows in one of the bus bars in a direction opposite to a direction in which current flows in the other bus bar, the inductance of the bus bars is reduced, resulting in the decreased fly-back voltage generated upon switching operation.

Abstract: A power supply is adapted to be powered from an ordinary electric utility power line, or alternately from a standby storage battery, and is operable to provide a power-line-isolated output of 120 Volt RMS at a frequency of about 30 kHz. The Volt-Ampere product available from this power supply is limited to be no more than 100 Volt-Ampere. Due to the high frequency, the electric shock hazard associated with this 120 Volt/30 kHz power supply is not higher than it is for a power supply voltage a voltage of only 30 Volt RMS at 60 Hz.The power supply is used to provide shock-hazard-free and fire-initiation-hazard-free electric power for an auxiliary power distribution system in a home. Due to the Volt-Ampere limitation and the absence of shock-hazard, the power distribution can safely be done by way of so-called bell wire installation and without requiring the services of a licensed electrician.
