Footswitch for GageWay PRO Interfaces This footswitch allows you to trigger a data send with MicroRidge's GageWay PRO Gage Interface Boxes. Used on floor as footswitch or on the tabletop as a palm switch. When the Footswitch is pressed, the MicroRidge GageWay Pro will go out and "ask" the gage for a reading. You can use 1 footswitch to control only 1 port, or all 4 of the ports on the GageWay PRO Gage Interface Box.
