idle up valves.. resistance/flow?

[oldcorollas]

Oh... a rotary switch from Jaycar would handle the current no problems.

Get this one:

Then parallel up the poles, so it then has 450mA switching ability.
That should be plenty. Even if the solenoids do pull more than 450mA, the switch will still last quite a long time.

i have this one already, so was thinking max of 300mA = 47ohms ish, but could probably reduce current to solenoid and still have it work. hence asking about the resistance of the valves

but i guess i could take it back and swap to the 3 or 4 pole versions

they look liek these.. 350mA@125V = foine http://www.made-in-china.com/showroo...2-SR2613-.html

then again... allt eh current will go through teh base legs.. hmm, maybe switch is not up to scratch..

Give it a try anyway, odds are itll be fine.

The main thing is that you must put a diode across the solenoid, or the flyback current when you switch it off will burn out the switch. Those little switches don't open the contacts very far, so without a diode you'll get arcing between the contacts.
