Hollow encoder with switch option

Hi guys.
We all know that standard encoder is widely available, but has any one saw rotary encoder that would be hollow in the center and has push button build in??

Thanks

There are hundreds of standard encoders. Can you give us a drawing of what you are describing?

A "standard" encoder would be like on your car stereo; you can turn it to adjust the volume or press it to turn the stereo on/off. He's looking for one with a hole down the center (a thru-shaft).

Personally I've never seen such a thing.

I guess this is his chance to drill a hole down a shaft and make a custom unit!

Or get one of these

Or check the "open center" parts.
