Amps rating

Theflyinglineman · 03-23-2019, 04:57 PM

Any ideas how I can find out how many amps this switch will carry?
This was a hazzard switch on my TXT. I would like to use it as a disconnect switch for a 20 amp 36v -12v reducer

I can't help with the rating, but are you using it on the 12 volt side or the 36 volt side?

Well, the 36v side should be 6.66-10 amp load at Max load. In that respect, the switch would likely be fine. The problem would be the initial inrush current, that's what will wear the switch out.

I wasn't sure whether he was talking about the 20 amp side, but the low current, high(er) voltage side makes more sense.

How do you plan on using this? Opening and closing under load would be worst case.

I was hoping to use it to turn the 20 amp reduced on and off on the 36v side. The reduced I bought does not have the ability to turn on and off via the key switch

So 1/3 of 12 volt amperage at 36 volts (really more due to losses).

As to "ability to turn on and off via the key", that's what a relay's sole purpose in life is. Well, not limited to reducers.

Did you look closely with a magnifying glass or something? It might be stamped somewhere.

Would you use a manual switch you can forget, or a relay you can't? They're like $5.

Do you think I would be able to find it locally?

If you have a local buggy store, possible. If you can Internet, definitely. A car or boat parts place probably won't have a 36 volt coil.
