Standards & Certifications

Flammability Standards:

Supplement

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.)
