Abstract
A potentiometer and switch assembly wherein the potentiometer resistance is deposited on a circuit board. The control member of the assembly comprises a shaft having a rotor mounted thereon, attached to which is a wiper for contacting the resistance. The switch mechanism includes a cam shaft adapted to be engaged by the rotor whenever the control shaft is pushed. The cam shaft is positioned to the side of the rotor and is rotated through a predetermined angle each time the control shaft is pushed. Camming surfaces on the cam shaft contact one member of the switch contact pair to alternately cause that contact pair member to open and close the switch. The cam shaft may be arranged to contact a second switch contact pair which opens and closes oppositely to the first switch contact pair so that a three-way switching function may be effectuated.
