Use a single-pole, two-position switch to reverse a motor without
swapping motor leads (Figure 7). The switch contacts should be
rated at a minimum of 125 volts and 150% to 200% of motor
nameplate current.

Warning
Do not change the FORWARD/REVERSE switch setting
while the motor is still running. Plug reversing the motor
(not allowing the motor to come to a stop before reversing)
will cause excessively high currents to flow in the armature
circuit, which can damage the control and/or motor.
