Abstract

889,984. Keyboard switches; switches held set and freed mechanically. SCHWEITZER, H. E. May 4, 1959 [March 24, 1959]. No. 15158/59. Class 38 (5). A push-button switch comprises a movable contact carrier 6 loosely mounted on a pin 5 and biased to the position shown by a spring 8. The pin 5 has a portion 5c rotatably carrying a sleeve 5d, and the latter has an axial slot engaged by a fixed pin 54 which can also enter axial grooves 53 in the portion 5c. The grooves open into a circumferential groove 50 bounded on one side by teeth 51 and on the other by teeth 52 offset from teeth 51 by half a tooth pitch. Thus successive actuations of the button 5a cause the pin 54 to act on the sloping faces of the teeth 51, 52 to rotate the portion 5c, so that the pin 54 alternately comes opposite grooves 53 which permit retraction of the button, and teeth 52 which do not permit such retraction. Specifications 677,376 and 813,965 are referred to.
