Abstract
A rechargeable battery jump starting device with a control switch (e.g. rotary control switch) and an optical position sensing switch system to determine the position of the control switch. The optical position sensing switch system includes an optical position sensor using optical coupling to insure the integrity of isolation on the 12V to 24V master switch to allow for a safe and effective operation, and configured so that the microcontroller unit reads the position on the master switch.
Claims15
A rechargeable battery jump starting device having an electrical optical position sensing switch system, the rechargeable battery jump starting device comprising:
- a first 12V battery;
- a second 12V battery;
- an electrical control switch electrically connected to the first 12V battery and the second 12V battery, the electrical control switch having a parallel switch position for connecting the first 12V battery and the second 12V battery in parallel, the electrical control switch having a series switch position for connecting the first 12V battery and the second 12V battery in series;
- a microcontroller unit electrically connected to the electrical control switch;
- and
- an optical coupler electrically connected to the microcontroller unit, the optical coupler providing a signal to the microcontroller unit for indicating a switch position of the electrical control switch.
