Abstract
A work machine having an engine, a hydraulic system powered by the engine, a source of electrical power, and electrical systems which run on the electrical power includes an ignition system and a modular ignition switch keypad to control the ignition system. The modular ignition keypad is mounted to the work machine in the operator compartment and generates a latching output to control electrical power distribution to the electrical systems and to control ignition functions to turn on and turn off the engine. The modular ignition switch keypad includes a start user input, a run user input, a stop user input and latching logic circuitry providing the latching output.
