Helmet switchy knob thing

[northwest]

I noticed today I have lost the switchy knob think off my ESAB Savage helmet, is this something I can easily buy and replace?



It is push for grind and rotary for darkness, is this a regular replacement part or unit?

stick the end of the finger off a rubber glove over it to heep the dust out , and be happy , as soon as you have spent half an hour messing with it ,,, you will step on the original that rolled out from under the bench , and break it ,,,
its just how welding is some days
