The engine coolant temperature switch is a
normally open switch. The switch contacts close at
approximately 221°F / 105°C. If the coolant
temperature rises above the switch point, the
switch contacts close and the engine will shut off
to prevent damage. The engine will not start until
the temperature drops below the switch point.
The engine oil pressure switch is a normally open
switch. The switch contacts close at approximately
4.27 psi / 0.3 bar. If the oil pressure drops below
the switch point, the contacts close and the engine
will shut off to prevent damage.

window at the ground controls when either switch
closes.
