Abstract
A potentiometer which can be used for measurement of angles includes an enclosure made of insulating material. The enclosure has a positioning portion comprising a pair of grooves to guide a resistance base plate into the enclosure. The enclosure is provided with a recess extending perpendicular to the plane of the base plate to rotatably receive the shaft portion of a sliding member. This sliding member further includes a slider which is brought into sliding contact with electrodes formed on the base plate. This produces a change in the resistance of a resistance member formed on the base plate.
