Reverse motor with switch Relay wiring to reverse motor shown in example above.

Motor must be OFF when reverseing direction
When switch is OFF, the relay is OFF so NC terminals connect wires inside the motor... motor runs forward
When switch is ON, the relay is ON, so NO terminals switch the wires to reverse motor
Use ordinary single-pole switch.
