Zepsus Magnetic Switch 7A (waterproof)


Zepsus does it again, this time a waterproof magnetic power switch rated for 7 amps.

  • This is a waterproof, switch that can be turned on or off via a magnet. No need moving parts, and can be located inside of something like a model sailboat. 

    The switch is very small and incredibly strong. With this switch, your equipment or model can be turned on or off without you needing to access it internally. Just move a magnet over the switch, on the outside, and it turns on. To turn it off just pass the magnet by the switch again. The switch has an ultra low standby consumption in the off-state. The consumption is so low that the switch can be connected to a 300mAh battery for several years without discharging it. The switch has a built-in failsafe function. It remembers its state for at least 10 sec, if disconnect from the battery. It will protect the switch against power glitches caused by bad battery connections, etc. 

    There are also many other things it can be used for such as rc submarine, diving lights, immobilizer for motorcycles and cars, etc.

    Production test

    All switches have been tested with 10A for 30 sec before delivery. Standby consumption is controlled and a visual inspection is made.
