We have been contacted by Tom Chalfant. He has been building RC models submarines in many years. He offered to test our new product, which is the Magnetic Switch 7A Waterproof. Below you see Tom Chalfant with his Seaview and a Jeff Porteus’ slightly larger version.
As Tom says: These subs run very much like the real subs. There are many different ways we submerge. We have systems that use a piston or pump that will bring in or push out water/air to change the buoyancy enough to submerge (Static diving) and others that use just forward motion to dive (dynamic diving). The electronics are kept in a WTC (Water Tight Container). This area usually stays very dry. The Seaview had an electronic switch, but it is not waterproof or resistant and condensation cause a short. I have been looking for a magenetic switch that would serve our hobby and offer protection like yours.
