1,082,437. Keysenders. SIEMENS A.G. Aug. 24, 1965 [Aug. 25, 1964], No. 36212/65. Addition to 1,082,056. Heading H4K. In a keysender wherein depression of a key causes longitudinal motion of one or more sliders, the latter have at least two working positions whereat they operate one or the other of two contact sets associated therewith. The end of the slider is shaped so as to co-operate with the spring arms 12 of the two contact sets 8, 9 whereby, depending on the direction of motion of the slider, one or the other set is operated and the particular arm 12 moved, provides a restoring force for the slider. In other respects the keysender is similar to that described in Specification 1,082,056. |
