Ignition Switch for MF Diesel Tractors & Loader/Backhoes w/ Cold Start & Ignition Step

4 position starter switch:

Step 0:  Off
Step 1:  Ignition
Step 2:  Pre-heat
Step 3:  Start with pre-heat

Step 2 and 3 are spring-loaded.

Used on mid-70's and newer models with Thermostart and ignition position (for powering instrumentation/accessories). See related products below for alternative ignition switches for older MF diesel tractors with pre-heat, but without ignition position (i.e. starts as soon as key is turned clockwise from OFF) and models without pre-heat or ignition position (just 2 positions: Off and Start - most US built models are like this).

• 4 terminals / 6 blades (see last picture for wiring schematic)
