It doesn't quite fit in my DIY pedal switch box that has 25mm internal height. The lugs are long and protrude upward. The drawing on the website indicates 22.2mm, but with one internal nut and no washers, it barely clears. To limit potentially shorting out on the bottom metal plate, I layered it with electrical tape. The lugs are contact solder only, no holes in the lugs, therefore no physical connection is possible before soldering. Nevertheless, its functionality is intact, and it works well for my purposes. The switch is low-cost, but for short shallow pedal boxes, I would recommend the Carling SKU P-H497, which is twice the price.
