Marquardt offers models with minor differences (e.g. only different contact materials) for many years. Now they use their experience for rework of the stock program. Marquardt has decided to prefer versions with Ag/Ag contact system instead of Cu/Ag.
Models with Cu/Ag contact system have silver only on the moving part of contacts (blue area on red part). Models with Ag/Ag contact system have silver on the fix part of contacts and on the terminal too (blue area on yellow part). Marquardt thus reduces the quantity of models with lower demand and by focusing only on Ag/Ag versions, it maintains high stock availability.
The silver on contacts makes the electrical rating better. For example, at 180x Series, Ag/Ag improves the rating from 10(4)A 250Vac to 12(4)A 250Vac and the inrush current from 50Amps to 70Amps.
Optimization concerns 180x and 183x series rocker switches. Original Cu/Ag models are being sold out but can still be ordered (respecting the minimum order quantities and the lead times).
Some of the new Ag/Ag types can now be found in our stock together with detailed datasheets.
