A routing machine comprises a base unit and a motor unit releasably connected to the base unit. The base unit includes a handle and a first electrical connector. The motor unit includes an electric motor, motor control circuitry configured to energize or de-energize the electric motor, and a second electrical connector connected to the motor control circuitry. The second electrical connector is configured to engage the first electrical connector when the motor unit is properly seated on the base unit. An electric switch is positioned on the base unit. The motor control circuitry is configured to deliver electric power to the electric motor when the switch is in an on position. The motor control circuitry is configured to not provide electric power to the electric motor when the switch is in an off position.
