Abstract
A slide switch having at least one row of terminals arranged along a substrate has a slider movable along the terminals. The slider carries a movable contact element biased resiliently towards the terminals so as to connect separate pairs of these terminals electrically together during movement of the slider. Each of the terminals has an exposed contact portion having an arcuate surface and the movable contact element has a generally corrugated shape formed by three arcuate protrusions forming convex surfaces facing the terminals and each spaced by trough portions presenting concave surfaces facing the terminals. In this way, the arcuate surfaces of the exposed contact portions can be adapted to fit within the trough portions upon movement of the slider into particular positions so as to stabilize the slider in these positions. Additionally, means are provided for pivoting the movable contact element as it disengages from an exposed contact portion so that the terminal last engages the movable contact portion at a location different than such engagement when the slider is in an associated stable position.
