(...) A quick check reveals that a replacement part for the polyswitch fuse is 60R250 (Littelfuse) or the Bourns MF-RX250...I'm sure there are others. If you can't find one of these resettable fuses, you could likely use any 5amp fuse and just (...) (25 years ago, 12-May-99, to lugnet.robotics.handyboard)
