Troller dual power pack

[peteski]

I never really needed that type of switch so I never really looked for one. I find Digikey search engine easier to work with than Mouser and I found what looks like 5 possible switches.  Check the dimensions of yours to get the right replacement.

Wouldn't drilling a round hole in the case and using a push button momentary switch be better as a "brake" application than a weird spring slide switch?

I agree.  I would prefer the spring-loaded mini toggle, but the idea is the same.  You probably would not even have to drill
unless you chose a large toggle or pushbutton.  It would probably fit through the rectangular hole and secure with a washer and nut.
With a little handywork, you could cut out a small metal or even styrene sheet painted black to completely cover the rectangular hole and make it look good, as well as be functional.

As I recall, Troller packs were UL Approved, which was one of the selling points in their ads, one of which showed a pack after UL's testing as a mangled mass of metal. Their choice of switch may have been dictated by clearance issues in the event of the case being dented....
