UL94V-0 rated housing & base
The ND3 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 SMT DIP Rotaries
Series ND3
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 vapor phase and
infrared convection reflow soldering.
Gull-winged terminals ensure mechanical
stability during soldering and simplified
solder joint inspection.
.100” (2.54mm) terminal grid spacing between
pin centers, plus 3-by-3 terminal arrangement for
pad layout pattern equivalent to industry standard.
Epoxy sealed terminals lock out flux, solvents, and other contaminants.
Packaging in tape-reel or partitioned tray. Tape-reel packaging meets
EIA-481-D Standard.
Coplanarity: all considered surfaces must lie between two parallel planes that are
a maximum distance apart of .0059” (0.15mm). (Additional coplanarity details in
Terms and Acronyms in the Supplement section.)
