Zepsus Dual Battery Magnetic Switch - 20 Amp


Small, very strong, and super reliable.

Availability: Out of stock

  • Designed for large scale RC gliders, where safety is a key component. Small, very strong and super reliable, due to it's redundancy feature.

    This is a very small power switch that has been designed for large scale model gliders. 

    The Dual Battery provides redundant functionality, which provides security. The switch simply selects the battery or BEC with the highest voltage. If the voltage is the same, the power is drawn from both batteries or BEC’s. If one battery or BEC is removed or short-circuit, it will not affect the other battery or the output voltage. The idea is to use 1S Lipo/4S NiMH or 2S RX lipo depending on whether RX lipo should be the main RX battery (2S) or backup battery (1S Lipo/4S NiMH).  

    As with all of our other switches, with this switch your RC model can be turned on or off without the need to access it internally. Just move a magnet over the switch, on the outside of the model, and it turns on. To turn it off just pass the magnet by the switch again. The switch has an ultra low power consumption in the off-state. The consumption is so low that the switch can be connected to a 1000mAh 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.

    Production test
    All switches have been tested at 20A for 30 sec before delivery. Standby consumption is adjusted and a visual inspection is made.
