A direct current motor controller includes a housing, a plurality of terminals, a first two-way switch, a second two-way switch, an actuating mechanism, and a remote controller plug. The terminals and remote controller plug traverse out of the housing as the first two-way switch, the second two-way switch, and the actuating mechanism are mounted within the housing. A first output terminal, a first power supply positive terminal, and a third power supply negative terminals from the terminals are electrically connected to the first two-way switch. A second output terminal, a second power supply positive terminal, and the third power supply negative terminal from the terminals are electrically connected to the second two-way switch. The remote controller plug is electrically connected to the second power supply positive terminal. The actuating mechanism operatively couples with the first and second two-way switches to toggle and inversely toggle the first and second two-way switches.
