Suicide switches, or cut out fuses, they are always great to find. Vi Brown had this 30 amp P&S [centre unit] on her table, but not for long. I was able to steal it away and add it to my small but growing collection. The interesting thing about these switches is the tremendous variety of styles, shapes and colours. I recently saw many of the different units Rick Soller had in his collection, so I still have a long way to go to catch up to Rick, but I am always looking for additional pieces of interest.
