Hi Kevin,

you say subminiature switches such as the C&K 7000-series and equivalent from Carling easily handle the voltages in question.

I do not really understand how to calculate VDC ratings from VAC ratings on these switches. For ex. switches have usually ratings such as 250VAC.

According to TOT p. 3-2 the peak VDC as I understand is usually VAC times 1.414. That means it is much higher.

How do I know if a switch can handle more than 300VDC? I have a switch that shows 3A 250VAC. What is the maths behind it?

Best wishes
Kai
