Does anyone know if the cycling switch uses an o-ring?

I removed the switch to gain better access to work I was doing in that area and when I went to put it back on, there is no o-ring inside the switch.

I wasn't sure if I lost it or if there wasn't ever one to begin with.

 

There should be one on the accumulator.

 

Thanks Quintin.

It would be easier with a picture, but I'll try to explain it with words. The Oring should be at the base of the accumulator, correct? So when the switch is threaded on, the switch compresses the Oring between the bottom of the plastic switch and the accumulator?

Thanks again.

 

Yes there is an o-ring for the cycling switch. Should be on the switch.
