Manufacturer profiles associated with Rotary Function Switch.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The number of positions typically ranges from 12 to 30, depending on the model and the number of measurement functions and ranges the multimeter supports. The exact number must be confirmed with the manufacturer for the specific switch model.
The contact rating is typically 2 to 5 amperes at 250 volts AC. This indicates the maximum current and voltage the contacts can handle safely. Always verify the rating for the specific application to avoid overloading the switch.
The mechanical life is typically 10,000 to 50,000 cycles without electrical load, while the electrical life is 5,000 to 20,000 cycles at rated load. These values are directory references and should be confirmed with the manufacturer for the intended usage.
The switch may be referenced to IEC 61010 for dielectric strength and IEC 60529 for degree of protection. However, these standards are listed as verification references and do not guarantee that a specific product is certified. Always check with the supplier for compliance documentation.
