ABSTRACT:
A variable resistor including an insulating substrate carrying a resistor layer and a rotatable slider has an insulating spacer separating the slider from the insulating substrate by an appropriate distance. The insulating spacer is formed of a synthetic resin molded directly on one surface of the slider and is integrally secured to the slider by having portions of the resin extending through holes formed in the slider. Thus, the number of overall components of the resistor is reduced to facilitate assembly and make management of the components easier.
