Stackpole discrete switch is a provisional name for a low-profile cruciform-mount keyboard switch from Stackpole.
A patent for the switch was filed in 1972. A later patent was filed in 1974 which introduced a revision to the switch: the ends of the horizontal spring—used as a bridging electrical contact—were capped with conductive silicone rubber to provide for increased longevity.
