This popular family is used in measurement and test instrumentation for range setting, data programming and count controlling; and in communications equipment for digital tuning. The simple, reliable bi-direction pushbutton mechanism permits rapid changes to either higher or lower numerical settings. Instrument-grade performance and long service life are enhanced by the heavy gold wiping contacts. Large readout characters are protected by dust-sealed windows. Snap-together grouping and snap-in panel mounting minimize installation time and cost. SMCD models have snap detent with slight audible click. SMCD bi-directional code switches may be easily assembled into groups of any number. The tabs or pins of one decade section press fit into the holes in the adjacent section. Spacers and end mounting plates may be included in the same manner as desired. Groups of SMCD switches with end plates snap into panel holes of the recommended size and are retained by plastic clips. Again, tools and additional hardware items are not required. 1 SMCD .193/.139 EXCEPT 301: .140 0.20 (5.08) HIGH NUMBERS .300 (7.62) .280 (7.11) .945 (24.0) .232 (5.89) 1.89 (48.0) .866 (22.0) 8 1.02 (26.0) 1.26 (32.0) AK TYPES 1.66 (42.1) AL & AL/D TYPES BOARD TRACE DETAIL AK TYPES .098 (2.49) .039 (.991) DIA.
