Safety Start Switch

This is a push button switch actuated by the clutch pedal. The switch is fitted on the clutch housing in front of the clutch pedal on tractors with L cab or without cab and on a bracket under the instrument panel on tractors with XL cab. Voltage supply is from the key switch in the No. 3 (start) position. When the clutch pedal is up, the switch has an open circuit.
