Abstract

1,131,999. Momentary actuation switches. EASTMAN KODAK CO. 24 July, 1967 [4 Aug., 1966], No. 33908/67. Heading H1N. Depression of button 13 causes conductive blade 17 to pass between normally closed contacts 18, 19 to momentarily open the switch. Blade 17 normally engages fixed contact 18 and as it moves down between contacts 18, 19 it cams a resilient portion 19b away from contact 18 (Fig. 3, not shown), the switch remaining closed until just after blade 17 leaves contacts 18, 19 at which the switch is open momentarily (Fig. 4, not shown). Release of button 13 allows blade 17 to return to its initial position by riding externally over part 19b, contacts 18, 19 remaining closed.
