<p>Potentiometer in which the contact (15) of a sliding brush (16) attached to a mounting plate (14) is pressed against a resistor member (9) and a collector member (10) mounted on a resistor-base plate (8) so as to obtain an electrical output from the contact. One of the resistor member (8) and the sliding brush-mounting plate (14) has a means for its position to be shifted independently by an external operation such that the relative position between the resistor-base plate (8) and the contact (15) of the sliding brush mounting plate (14) is externally adjustable. Thus, in the state wherein a rotary driving shaft (7) or a linear driving lever is so controlled as not to shift to any arbitrary position, it is possible to externally adjust the initial electrical output of the potentiometer to a predetermined value quickly, easily, and accurately.</p> |
