An electrical circuit for connecting an electric motor to an electrical source of supply comprising a double pole single throw switch having four quick-connect terminals thereon. Two of said terminals are connected to the electrical source of supply and the other two of said terminals connected directly to the windings of the electric motor. A centrifugal switch is provided, mounted internally of the housing of the electric motor on an insulated electric circuit board. The supply leads bypass the electric circuit board on which the centrifugal switch is mounted, thus minimizing the number of terminals and electric circuit connections and increasing the reliability and safety of the circuit.
