Abstract

A switch assembly includes a shaft, a first switch and a second switch, a potentiometer including a first and a second terminal, and an electric controller. The first switch is coupled to a first device, whereas the second switch is coupled to a second device. The shaft is coupled to the first switch and the second switch, and is moved to a first position to selectively connect power, through the first switch, to the first device, and to a second position to selectively connect power, through the second switch, to the second device. The potentiometer is coupled to the shaft, and provides a variable resistance between the first and the second terminal in relation to the movement of the shaft. The electric controller is coupled to the potentiometer, and electrically controls the power to the first device and/or the second device in relation to the variable resistance between the first and the second terminal of the potentiometer.
