Need help locating a jog switch
 

I'm having a hard time locating a part I need for a new project. What I'm looking for is a rotary switch that if you turn the shaft clockwise 30 or so degrees it closes a contact, if you turn the shaft counterclockwise it closes a second contact. The switch should return the shaft to the center once it is released. Like a jog dial on some VCRs.

Ideally the switch would have a 1/4" shaft, but I could deal with slightly larger or smaller.

Thanks in advance for any help.
