engine, turbine, or other type of prime mover, to protect against
runaway or overspeed with possible personal injury, loss of life, or
property damage.

The micro switches are used in one of two ways.
1.
They energize a light which indicates the motor has reached its minimum or
maximum speed-setting position.
2.
Instead of energizing a light, they may be used to shut off the electric motor
after reaching the minimum or the maximum speed-setting position.
When used to shut off the electric motor, micro switches also protect the
synchronizer (speed setting) motor should the operator run the speed adjustment
to its limit.
The external wiring to the governor is not provided by Woodward and should be
wired into the connector for the particular application as required.
