Thumbwheel Switches 7000

The 7000 series combines heavy duty construction
and a compact package size.

Designed to meet demanding military
performance requirments, the 7000 series
features a unique one piece housing design,
sealing the contacts from moisture, dust and
dirt. The 7000 series is available in either P.C.
board or cable termination styles, and many
8, 10, 12 or 16 position binary or decimal
output codes.

Options include lighting, EMI/RFI shielding and
double wide message units. Lamps are easily
replaced without tools on lighted models.

Typical applications include aircraft, shipboard and harsh industrial environments.
The 7000 series is backed by a one year warranty.
