ABSTRACT:
A programmable, electronic switch system in which the upper and lower limits of travel of a moving device can be stored in the memory of a circuit. Once the upper and lower limits of travel have been programmed into the circuit, movement of the device causes a variable voltage to be output to the circuit. The variable voltage is compared against the upper and lower limits to determine if the voltage is within the range between the upper and lower limits or outside of one or either of the upper and lower limits.
