Abstract
1368980 Mechanical switches TEKTRONIX Inc 23 Dec 1971 [10 Feb 1971] 41292/73 Divided out of 1368977 Heading H1N In an attenuator switch of the type described in the parent Specification 1,368,977 a bridging contact 96 is supported by an insulating block 100 or 102 resiliently mounted on a metal leaf spring 98. The fixed contacts 92, 94 may be printed circuit contacts on a board 58 to which sets of leaf springs 98 are attached in pairs by common rivets. The contacts 96 are activated by a rotary cam 28 as described and claimed in Specification 1,368,979.
