Purpose
Used as part of the safety interlock circuit, it is typically used to monitor the
position of the PTO or brake lever.
How It Works
This SPDT microswitch has three terminals. The lever is spring loaded in
the “up” position. When the lever on top of the switch is pushed, continuity
switches from COM1 and NC2 to COM1 and NO3.
Testing
1. Disconnect the switch from the wiring harness.
2. Verify the conditions in the table.
Part Numbers

Purpose
Typically used to turn on the electric blade clutch and to function as part of
the safety interlock system.
How It Works
Contacts inside this DPDT switch electrically connect various terminals. It
is actually just two SPDT switches tripped by a single lever. One of the
SPDT switches is connected to the electric PTO clutch. When in the off
position, this side of the switch is open. The other half of the switch is used
by the safety interlock system. When the clutch is off, this side of the switch
is closed. This allows current to keep the kill relay energized so that the
mag is not grounded out.
Testing
1. Disconnect the switch from the wiring harness.
2. Verify the conditions in the table.
