Push-Button Ignition Switch

The push-button ignition switch is used instead of a conventional ignition switch to achieve the various ignition modes. The push-button ignition switch is a momentary dual contact switch. Both sets of contacts are normally open and receive voltage at all times. When the START/STOP button is pressed, the voltage signals sent from the RFA module are routed to ground, pulling the signals low to indicate a button press.

The ignition switch has a LED for switch illumination when the backlighting is activated.
