PCB Processing
Soldering:
Cleaning:
Wave Soldering recommended. See Profile A in Supplement section.
Manual Soldering: See Profile A in Supplement section.
Automated alcohol based cleaning recommended, 5 minutes maximum. Do not use high-purity
alcohol (50% alcohol or more) or organic solvent. High alcohol solution can damage clear plastic.
See Cleaning specifications in Supplement section.
Standards & Certifications
D8
The GB Series illuminated pushbuttons 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.
