DRYER
SAFETY SWITCHES
The centrifugal switch slides back and forth on the motor’s shaft to operate the
contacts as shown in the previous diagram. This switch provides safety in the
event the motor fails. When the motor is running, centrifugal force causes the
weight (black wing in photo) to slide back toward the motor windings. This motion
allows electricity to operate the heater (electric element or gas valve). If the
motor stops, the weight slides forward and turns the power off.
RUN POSITION
STOP POSITION
There is an additional safety in the form of a belt switch that shuts off power to
the electric motor if the belt breaks. Belt tension holds the switch closed. If the
belt breaks, the switch opens and power to the motor is cut. When the motor
stops, the centrifugal switch functions as a safety device to turn off the fuel (gas
or electricity).
The centrifugal switch includes a multi-
pin connector (shown).
The belt switch is simple. If the belt
breaks, the spring pulls the lever down
and it presses the switch.
