This is really puzzling me.
I have a cold plunge barrel which has a waterproof light in the bottom
It is a low power LED set up with a constant current transformer from the mains powering a single LED bulb. See pics.
Decided to put an outdoor switch between the transformer and the lamp to make it easier to switch on and off.
Now when you operate the switch the light bulb blows. Can’t work out why. Have checked current to lamp and all fine per transformer spec and don’t see why putting a switch in would change that?
Any ideas ?
