for those that do not know,
NC (normally closed) means that the circuit is complete until the button is
pressed. You will need to change the switch to NO (normally open) which means
the circuit is open / incomplete UNTIL the button is pressed. When the button
is press and the NO contacts CLOSE to COMPLETE the circuit, this will ground
the ignition circuit and kill the engine.
