ABSTRACT:
A self-referencing position switch particularly adapted to respond to the position of an automobile gear shift lever. The switch is responsive to the position of a movable external member relative to a stationary member and includes a pair of housing sections one of which is attached to the stationary member and the other of which defines a track for a movable switch member which follows the movements of the external member and is arranged to close the switch at a selected location along the track. The two housing sections are movable relative to one another in more or less the direction of the track so that by engaging the movable switch member against one or the other end of the track and moving the housing sections relative to one another, the selected location on the track can be correlated with a selection position of the movable member.
