Am trying to find the flip lever for a rtx3 type 1 rotary tool. B&D website shows a button and pin replacement and talking with them they only show that too. Has anyone got a replacement part number? The small lever locks the motor while you unsrew the tool and also prevents the motor from being started by lifting the small lever twoard the front.It is a registered part of this dremmel type tool. Have tried e-replacement tools etc. without any success. It's like they don't exist, but I see them at stores, advertised all the time. And have one.
