The Cole Hersee catalog rates most of the switches at 12V DC. Can they be safely used in a 24V application?

Sometimes. Items such as Solenoids and Illuminated Switches must be used at the rated current and voltage due to the internal components. Ignition, push-pull, momentary, door and other types of non-illuminated switches can be used in a 24V system, with one proviso.

For a 24V application you must de-rate the current capability of a 12V product.. Using Ohm's Law, if you double the voltage, you must divide the current in half. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
