I have a Microair transponder which has some type of an internal electrical circuit that uses on shutdown. In cases of low voltage it simply will not shut down. In a couple of instances after very long flights I was getting to critically low battery voltage and was going through a sequenced shut down of equipment. When I got to the Microair, it would not shut down because of the low voltage. Fortunately I had the fuse on the panel and with my thumbnail could shut it down that way.
For what it's worth,

My big winter glider project is going to be re-doing my control panel. I have been looking at a lot of panel pictures recently and I notice that a lot of them have panel mounted fuse holders all over them. My experience with our panel mounted electronic gizmos is that if they blow a fuse, replacing it inflight is not going to do anything for you. Once the magic smoke gets out it's gone. So I'm looking at a terminal strip that incorporates the mini blade type fuses into the strip, and reducing the number of holes in the panel.

Has anyone ever replaced a glider fuse in flight and had something good happen?
