Abstract
1363140 Magnetic switches BUNKER RAMO CORP 26 Aug 1971 [23 Nov 1970] 40126/71 Heading H1N In order to ensure that all the switches of an array function at the same point in the stroke of their push-buttons a permanent actuating magnet 25 is longitudinally adjustably positioned on the push-button 12 of each switch or the contact unit 26 is axially adjustable. The permanent magnet 25 closes a sealed magnetic reed contact unit or units 26 when depressed. The magnet 25 is mounted in a socket 31 of the push-button and is biased into engagement with an adjustment roll pin 37 frictionally held and longitudinally adjustable in a passage 38 formed in the push-button. The position of the pin 37 may be automatically adjusted to set the operating position of contact unit 26 (Fig. 13, not shown). The push-button 12 has a pair of resilient fingers 39, 40 with integral projections 41, 42 by which it is retained in the main body 36 of the housing, the projections 41, 42 cooperating with retaining stops 43, 44 of the housing 36. The contact unit 26 is mounted on terminal tags, e.g. 13, for connection to a printed circuit board, not shown.
