Abstract

1,251,639. Stencil switches; fluid-pressure actuation. INTERNATIONAL BUSINESS MACHINES CORP. 29 June, 1970 [24 July, 1969], No. 31372/70. Heading H1N. [Also in Division G4] A fluid-pressure actuated diaphragm switch assembly 10 Fig. 1 for use in a parallel array for a row-by-row punch card verifier comprises a diaphragm assembly 23, Fig. 4 carrying separate contacts 42 for selective engagement with fixed contacts (31) Fig. 2 (not shown) on a printed circuit board 20. The assembly 23 is divided up into eight separate diaphragm areas defined by regions of non-stick material 36 surrounded by an adhesive 37 on an apertured backing 34, each area being associated with a particular punch 13 by a passage 15 in block 45 through which air is blown from inlet 14 to the particular passage 47 associated with one of the diaphragm areas. Each area is coated with a contact 42 having a spiral connector path 40 to a common terminal 41.
