ABSTRACT:
The control part of the slide member in contact with electrodes of a variable resistance with resistance members and a plural number of electrodes is made larger than the insulation part between two adjacent electrodes so as to secure the conductivity between the electrodes and the slide member. The form of the slide member and the space provided between each electrode part with respect to other such parts satisfy a predetermined mathematical relationship.
