SMCD Series

Pushwheel Switches, Mini, Front Mount

SMCD Series have large visible readout characters despite it's small

MATERIAL SPECIFICATIONS:

size. 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.

PC Board............................................Glass epoxy type, FR4

PC Terminals ....................................Gold over Ni on Cu

Character Height/Color......................White on black background

SMC .197/.134; SMCD .193/.134

Except 301 & SG558: .140 and

SG557 .120

Molded parts ......................................Noryl-SE1, Black matte finish

Housing..............................................Black matte finish

TYPICAL PERFORMANCE CHARACTERISTICS:

Contact Rating ......................................0.4 VA @ 20 VDC or Peak AC

Contact Circuit Resistance ....................0.12 Ohm max. (Total internal ckt. res.)

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.

Mechanical Life ....................................More than 10 operations

Operational Force..................................Approx. 14 oz.

ENVIRONMENTAL SPECIFICATIONS

Operating Temperature......................(-20°C to +80°C)

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.
