(...) Use a resistor to make one of the states of the switch read less than a full short. Setup as a light sensor. 0 means off 50~ means one state and 100 means another. This is the basis for alot of the touch sensor multipliers. I am sure if you (...) (23 years ago, 25-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

(...) But... be aware that the 'polarity switch' has only two connectors (for two sets of wires). It's not a '3-way' where you can try to select one of two inputs by moving the lever. The action is forward-off-reverse with one power source connected (...) (23 years ago, 25-Mar-02, to lugnet.robotics, lugnet.robotics.rcx)

(...) Well the polarity switch can be made to work as a "switcher" that can be used to can input source or output source by wiring it like Hao-yang Wang did in this example: (URL) works great like this, I use it with my RailRacers ((URL) control (...)

(...) Actually, you want it to be unpowered instead of powered; giving the sensor power will just waste your batteries heating up the resistors. Setting it up as SENSOR_TYPE_NONE and SENSOR_MODE_PERCENT (or SENSOR_MODE_RAW) under NQC would be much (...) (23 years ago, 25-Mar-02, to lugnet.robotics)
