The switch mechanism cracked in my magnifying lamp. No ballast. Just a

enlarged.

Thanks.



I had to replace the switch on my bench magnifier lamp (long ago
swapped-out lens with an ex-epidiascope bulging lens for bigger mag),
normal switch.
Does have ballast in the base and a starter "lamp" but I wonder if
excess current makes the switches fail more than usual.
