Smart-Switch
- 6 -
To switch off: hold the sensor button pressed in for about 0.5 seconds until the LED glows
orange, then press the button briefly a second time. The LED goes out, and the Smart-
Switch is switched off.
To switch on: hold the sensor button pressed in for about 0.5 seconds until the LED glows
orange, then press the button briefly a second time. The LED glows green, and the switch
is on.
The process of pressing the button twice, with a precisely defined interval, eliminates the
possibility of the switch being turned off accidentally, e.g. by vibration.
If the LED glows orange or red instead of green when you switch the circuit on, this
indicates that the battery connected to it is not fully charged or is already discharged;
alternatively the incorrect battery type might have been set. If this should occur, we
recommend that you recharge the pack using a suitable battery charger before using it
again; alternatively set the switch to the correct battery type.
The current handling capacity of the Smart-Switch stated in the Specification does not
relate to the switching capacity of the electronic switch, but to the limitations of the two
connecting leads (conductor cross-section 0.34 mm²) and the gold-plated Uni connector
contacts (JR, Futaba). Cooling is not required with the Smart-Switch. In electronic terms
the switching capacity of the Smart-Switch is more than 20 A, and if the current should
approach anywhere near this value, the leads and the Uni-connector would burn out long
before the switch was affected.
If the Smart-Switch is left connected to a battery when it is switched off, the unit goes into
“stand-by” mode. The idle current in this state is around 5.0 µA, which is lower than any
battery’s natural rate of self-discharge. Even so, we recommend that you disconnect the
battery from the switch if you know the model will not be used for a long period.
Please don’t just throw away the inner packaging, as it is designed to be used as a
template for marking the switch aperture on the model. Cut the opening using a knife or
saw, working slightly outside the marked line (see photo).
