Abstract

1,118,926. Position control. BURGESS PRODUCTS CO. Ltd. 19 July, 1965 [18 July, 1964], No. 29713/64. Heading G4H. A multi-position switch is set in accordance with the desired position of a movable member, each contact of the switch is connected to a corresponding junction between a pair of microswitches in a set connected in series, one end microswitch is connected to means for moving the member in one direction and the other end microswitch is connected to means for moving the member in the other direction. the arrangement being such that a circuit is completed to drive the member towards the desired position until an actuator e.g. a cam, coupled to the member opens the pair of microswitches on each side of the selected junction. Reference has been directed by the Comptroller to Specification 974,482.
