Abstract: A battery switch including a housing having a removable side panel, a base, and two terminals located within the housing. Each terminal has a fixed end and a free end. Each terminal extends upwardly from the base. Each free end is positioned in a space between the base and the housing. Wherein the free ends of each of the terminals are accessible by removing the side panel.

Abstract: A battery switch including a selector supported by a housing and rotatably mounted to the housing. The selector having four positions, including, a first position in which a first and second bank terminals are disconnected from a first and second load terminals, a second position in which the first bank terminal is connected to the first load terminal and the second bank terminal is disconnected from the second load terminal, a third position in which the first bank terminal is connected to the first load terminal, the second bank terminal is connected to the second load terminal, and the first bank terminal is disconnected from the second bank terminal, and a fourth position in which the first bank terminal is connected to the first load terminal and the second bank terminal and the second bank terminal is connected to the second load terminal.

Abstract: An apparatus for balancing a plurality of cells in a battery includes common bus having a connector for connecting to a common bus of another battery. Each of plurality of balancing circuits has a bidirectional voltage converter connected to a given cell of the plurality of cells and a linear current regulator arrangement controls the magnitude of current flow between the bidirectional voltage converter. A controller is connected to the common bus and the plurality of cells and selectively operatives the plurality of balancing circuits to transfer energy between the plurality of cells and the common bus to balance the states of charge of the cells. The balancing circuits are operated in response to actual states of charge of the cells, an average state of charge, a desired voltage level for the common bus, and an actual voltage level on the common bus.

Abstract: A power Y-adapter provides power at a high voltage to an output end from at least two input ends to which power of a lower voltage and a phase difference is provided and includes a first polarity sensitive current isolation device, a second polarity sensitive current isolation device, a control section, and an output section. When the voltage signals supplied to the hot wire terminals of the first input connector and the second input connector sufficiently are out of phase, the Y-adapter can produce a voltage of higher magnitude between the first and the second hot wire terminals of the output connector.

Abstract: A moisture release valve for an outdoor light including a valve body having a stem received in a valve guide and having a head seating with a valve seat integrally formed of part of a sidewall of a light casing of the light fixture. Valve body is gravity displaced between a closed position and an open position depending upon light fixture orientation and can include a counterweight carried by its stem interiorly disposed within the fixture helping to cause displacement of the valve body toward the desired open or closed position in response to a change in light fixture orientation. Valve body can be a rivet, such as a split rivet, and the counterweight can be a washer, such as an annular washer, having an opening generally in registry with the valve guide permitting fluid within the fixture to drain from the fixture when the valve is open.
