Strict but perfect

Turning the switch requires a bit of force, but that's perfectly acceptable for precise contact closure. Compared to cheap Chinese products, this and similar models are used by these shipyards even in the most expensive boats. Quality costs money, but it works... for a long time.

Topo quality

The switch is perfect - switches very tightly and well. The sturdy frame makes it very easy to attach to smooth surfaces and you can rotate the frame as needed so that the cables can be connected easily.
