Power ON/OFF - Rotary Switch

[derik736]

Hi,

I look for 3 position power rotary switch for my tube monoblocks. The problem is, it must handle a current of 3A and app. 600V. I need 3 positions: OFF / STBY / ON, it will be w power switch for my EL34 monoblocks. Any idea where can I find anything that can handle this kind of current? At the moment I use some medicore chinese ones, which are dead after one week so the monoblocks can´t operate properly.

I would be very thankful for any advice. I actually found very interesting vintage switches from soviet and East Germany military here:

Unfortunately there´s not much info about and specifics. I´m also not very flexible with the size, it would be great if the shaft diameter would be 6mm and at least 20mm long.


Thanks

If you've got the space you can always use a smaller switch and some relays.

The heater supply once rectified will easily drive some 12V relays.

I actually thought about that, in worst case scenario it will end up this way..

Try RS, Farnell, Mouser etc.

so you're gonna put your fingers on a switch that has 600V inside it - I'd rather have relays.

Do you mean DC or AC? 600V DC is VERY hard to switch, it would be much easier to use a high voltage mosfet

I know it´s pretty damn dangerous but the guy who build my amps apparently didn´t think about that..
