DEFINITION

Classification: 315/316

(under subclass 313) Systems wherein the switch for controlling the load device circuits is (1) a switch wherein the contacts are controlled by either a perforated card, sheet, or strip, having the perforations arranged as a pattern so that the number and/or the location of the perforations determine which of the switch contacts are to be operated or (2) a pattern member having a particular shape which cooperates with the switch contacts to determine which of the switch contacts are to be operated, or (3) a switch which is provided with a keyboard consisting of a plurality of manually actuated keys, each of which controls the operation of the switch contacts associated therewith.
