DC light switches ?

broadgage

Can anyone suggest a supplier of domestic light switches suitable for 250 volts DIRECT CURRENT.

I asked this in the old forum, and IIRC a respected member suggested a supplier of “heritage looking” switches but these were in fact still AC only.

Have previously obtained NOS switches from fleabay but these are now hard to find.

    Those Carling EK or DK ones are particularly good, with an insulation rating 1000VDC to the frame or across open contact  ( and you could earth the toggles)  

    But at nearly 2 inches long they are quite bosky.

    More info  

    “The quick make/quick break contact mechanism is ideal for high voltage DC applications.”

    But  I agree, most normal AC switches are not good at DC above a few tens of volts.

    Not sure about over-voltage category II/III in the case of battery powered lights, you could put a plug and socket in the way and magically lower the category ;-)
