Warco 290V push button

Well following my post on The tea room about my green on button shooting off into the stratosphere, still can't find it so thought I would continue my post on here.

I suddenly remembered I had a spare somewhere, think I must have had the same problem way back and got a spare but managed to fix the original.

The push button assembly connects with the contactor unit behind a plate, removlng said plate revealed a plastic lock nut to hold the button assembly which I have undone but cannot see how the contactor part pulls away from the button assembly, don't want to force it for fear of just breaking it, anyone done this before is there some technique or clip that needs removing to separate the two?

Sorry title should of course read Push button.

Oh it does!! when I looked at it on the Edit post it said Oush button,

Worry no more guys, ease your furrowed browes, I have sorted it.

Further investigation revealed a plastic tab which after much pulling and pushing I found it swivelled to one side releasing the two parts.

But, have another problem, the power on indicator is not working, probably hasn't for a while to be honest. Rating on the bulb, sorry lamp, is indistinct, could be 12, 2.2 or 20V.

Any clues anyone?

Bill D.

What fitting is the lamp? If you cannot find two out three voltages in that fitting-style, it is a clue.

Poke your tongue into the contacts. 2.2v will make you jump less high than 20v. A multimeter givea a more quantitative reading.

If all else fails, use ameter to measure the voltage at the contacts (If it is there)

Wouldn't feel inclined to be kissing an unknown voltage source!

Had another look at numbers on cap with aid of a magnifying glass.

Pretty sure it says 220V. No wattage indicated.

Cap diameter 9mm so assume designation would be BC9 or B9 or BA9 from what I have read.

Sent message to Warco to check.

Bill D.

Had a very speedy and friendly response from Peter in Warco spares. He said he was unable to check as current machines don't have a light but from memory they were 24 volt. He later asked around and concensus was they were 24V 2.2W. Size is BC9 so 9mm diameter bayonet cap.

Not easy to find but finally found some on Easy Light Bulbs site so ordered a couple.

Hadn't realised there were so many diffferent types, sizes, wattaage, volts, must be thousands of combinations, not the type you are likely to find on screwfix et al sites, not even Amazon turned anything up.

Fingers crossed for when they arrive.

Bill D.

Well got my bulbs but back to square one, fitted new one but still no light.

It's not end of the world as I have been using the lathe for some time without this power indicator working but just intrigued.
