Review on Aleph DC 1561 Surface Magnetic Contact by Callie Boyd

Great value for money. I wanted to test them before commenting. They arrived on time, are small, easy to install and work very well. The operating range of the magnets is approximately 1 inch for a parallel magnet and approximately 1/8 inch for a perpendicular magnet. This offers mounting flexibility without having to resort to spacers or the like. The magnets and reed switches are the same size (excluding the pins). ) - 1.125" x 0.25" x (0.25" + mounting tab 0.25" wide x 0.0625" thick - so nominally only 1/2"), and both have double 3M- adhesive foam. Mine also came with screws - Small 1/2" sheet metal screws that work well with wood or metal - I think for those who don't trust adhesives. The seller (Zbeem) sent a confirmation email with a special link, in case there were any shipping issues (a really nice touch that I've never seen).I appreciate your workmanship, timely delivery and the quality of the items.I've just ordered a few more to use in lockdowns.good product
