How It Works

Contacts inside the switch electrically connect various
terminals in both "On" and "Off" position. When the
PTO is pulled out to the ON position, current fl ows to
the electric clutch and it engages. When the switch is
pushed in to OFF position, current fl ows through the
PTO switch to the Park Brake switch as part of the circuit
used to ensure safe starting.
