Abstract
A co-ordinate switching system for a matrix of rows and columns of conductors includes mechanical elements at each intersection. The individual intersection connection is controlled by a circuit associated with the columns and common to each switch element and a second circuit associated with the rows. The matrix is made up of 'GO' and 'RETURN' conductor paths (114, 115) set up at right angles to each other, each junction having a ferromagnetic pole piece (118, 118a', 118b, 118b') in each right angle so formed and set in an overall 'yoke' (117). The pole supporting plate is set in the plane of the matrix as is the armature (111) pivoted at its centre which itself is at the matrix intersection centre. Currents in the conductors energise the armature and reverse it position.
