Product description


The SmartSwitch is ideal for all applications where security has top priority, but voltage regulation is not required. The micro-controller by which the On / Off switching system is controlled makes the SmartSwitch the perfect substitute for a mechanical switch.

The on / off switching process is initiated by pressing the push-button twice. The micro-controller monitors the sequence, and turns the electronic switch on or off if the procedure is valid. This eliminates any danger of operating the switch accidentally, and produces a connection which is resistant to vibration. The switch is a latching type, i.e. it stores the last switched state. This means that the system always remains switched on even if there is a brief interruption in the circuit at the battery end.

A further safety feature of the SmartSwitch is the integral voltage monitor: the tri-colour LED indicates the battery's state of charge in four stages. The voltage monitor can be set to suit all commonly used battery types: 2S LiPo, 2S LiFePo, 5S NiMH or 4S NiMH.



The SmartSwitch requires no cooling in operation. The switching capacity is more than 20 A, and in practice the limiting factor is the connecting cable.

As already mentioned, the SmartSwitch is not fitted with a voltage regulator, and for this reason it does not constitute a means of operating standard 6 V servos with LiPo batteries. Naturally HV systems can be operated with LiPo batteries without problem, and suitable servos can be operated directly with LiFePo batteries.

Two different connector systems are available at the battery end: Uni or MPX types. The MPX version is supplied as standard with two receiver connecting leads.
