Not that I'm encouraging anyone, but it has baffled me since I was a wee child.

Just how do you get the penny into the fuse socket without electrocuting yourself and have it STAY in there? Did people shove the coin into the socket and screw the burned fuse on top of it?

I've been trying this with a vertically mounted lampholder (disconnected) and USA coins of various sizes.

A 25 cent piece seems to fit the best....but it tops over and still falls out.

Have any of you run across things like this in the trade? Are there any pictures?

I've run across cartridge fuse holders with pieces of #12 wire across the clips. [Linked Image]

I would never post this sort of thing on a DIY board but since I'm among pros and semi-pros here...I assume that this is reasonbly safe to ask without giving anyone ideas? [Linked Image]
