Trying to re-engineer a mechanism which is cooled to 77K. The motors and microswitches keep failing at these temps. I need to change things. Does anyone have any suppliers of cryogenic rated microswitches and encoders. I need high repeatability so need a datum switch and step counting is not working to well. Small ones are essential due to tight space sonstraints.

cheers
