Abstract
A switching control device having a plurality of displaceable fingers programmable for controlling a sequence of switching operations in a time-controlled system has a magnetic element for exerting a magnetically retentive force on displaced fingers to hold the displaced fingers in displaced or programmed position, and permitting easy release of a displaced finger upon cancellation of a program so that the finger can return to an unprogrammed neutral position. The fingers may be mounted in a control disc having a permanent magnet or an electromagnet, the control disc functioning as a magnetic yoke, or the fingers themselves may be magnetic.
