Abstract
A battery master disconnect switch includes a front panel and a back panel. The front panel has a selector knob for selecting between multiple positions. The back panel has a primary terminal, a secondary terminal, and an auxiliary terminal. The primary terminal is for connection, using a first cable, to a primary battery. The secondary terminal is for connection, using a second cable, to a secondary battery. The auxiliary terminal is for enabling a device. The device receives power for any of the positions of the selector knob. The battery master disconnect switch can present a voltage for the primary, the secondary, or both the primary and secondary batteries.
Claims16
A battery master disconnect switch comprising:
- a back panel comprising:
- a primary terminal adapted to connect to a primary battery;
- and
- a secondary terminal adapted to connect to a secondary battery;
- a front panel including:
- a selector knob selecting between a plurality of positions, including:
- a first position for activating the primary battery;
- and
- a second position for activating the secondary battery;
- a battery voltage indicator which visually displays a voltage based on a voltage measurement of the primary battery;
- a second battery voltage indicator, wherein the battery voltage indicator visually displays the voltage based on the voltage measurement of the primary battery and the second battery voltage indicator displays a second voltage based on a second voltage measurement of the secondary battery;
- wherein the selector knob is further selectable in a third position for connecting the battery voltage indicator to the primary battery and to the secondary battery;
- wherein the battery voltage indicator visually displays the voltage, and the second battery voltage indicator visually displays the second voltage, in response to the selector knob being in the third position.
A battery master disconnect switch comprising:
- a front panel including a selector knob to select between a plurality of positions;
- a back panel including:
- a primary terminal to connect, by way of a first cable, to a primary battery;
