UL94V-0 rated housing & base
The ND Series rotaries have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.

8mm Process Sealed DIP Rotaries
Series ND
Toggles
Detent mechanism designed for crisp,
positive action for accurate switch setting.
Bifurcated, spring loaded contacts give
unmatched logic-level reliability.
Heat tolerant resin used for body meets UL
flammability rating of 94V-0 and maintains
switch reliability through automated soldering
process.
Crimped terminals ensure secure PC mounting
and prevent dislodging during soldering.
.100” (2.54mm) terminal grid spacing between pin centers,
plus 3-by-3 terminal arrangement for footprint pattern equivalent
to industry standard.
Epoxy sealed terminals lock out flux, solvents, and other contaminants.
