Abstract

A slider for resistor or slip conductors. The slider includes a generally U-shaped slider support having a center portion and two legs, leaf springs attached to each one of the legs and extending into the interior of the U-shaped slider support, and contact means guided by the leaf springs and kept in engagement with the resistor or slip conductor. In accordance with the invention, one of the leaf springs supports the contact means, and the other leaf spring resiliently engages the first leaf spring on the side remote from the resistor or slip conductor.
