Foot Switch Adaptation:We used to use the Foot Switches available at Radio Shack. For a couple years now we have been unable to find those particular ones. Action Electronics does have them in close out so you may want to call and check. But for an alternative foot switch check these out.Foot Switch from Action Electronic30-17090 Momentary SPST This one is momentary and RED,
30-17092 is a latch switch and BLACK.$10.95 plus shipping A small clip on the silver rod keeping the switch together needs to be removed. Removing the silver rod allows the top to come off the switch. Remove the spring in middle of switch and glue some some foam in the switch that doesn't interfere with the action of the small momentary switch. Make sure the foam is soft and has some resiliency. Place the top on to test the switch before returning the rod. You may have to adjust the thickness of the foam to acquire the sensitivity you desire. Place the top back on and return the clip to keep rod from slipping out.Top of switch has nice tactile rubber but may need extra sticky loop Velcro to stay to attach your picture communication symbols.Use either a 1/4 to 1/8 inch adapter or remove the 1/4 plug and replace it with a 1/8 " plug. Adapters are available at Radio Shack.RadioShack plug adapter link$2.69
