Smart-Switch
- 4 -
Operation:
The only control on the Smart-Switch is the push-button, which makes it extremely easy to
use. All this button does is pass the switch signal to the electronic switch; it has nothing to
do with the actual switching of the current.
Connect a battery of your choice to the battery lead, which is fitted with a Universal
connector (JR, Futaba). The pack may be a four-cell or five-cell NC or NiMH type, or a two-
cell (7.4 V) LiPo or Li-Ion battery. Take care to connect the pack with correct polarity.
Caution: the Smart-Switch does not feature a voltage stabilization circuit.
If you wish to use a two-cell LiPo battery, you must not use the Smart-Switch in
conjunction with a receiving system designed only for 6.0 Volts, i.e. the entire system -
receiver and servos - must be designed to cope with this voltage. If the receiving system is
only designed for max. 6.0 Volts, we recommend the Digi-Switch (also in our range), as
this features a supplementary voltage stabilization circuit which generates 5.5 Volts; the
switch housing is the same size.
If the Smart-Switch is to be used with a two-cell LiPo pack, one application which we
particularly recommend is as a switch for ignition systems which are designed as standard
for more than 6.0 Volts.
Caution: connecting the battery with reversed polarity will destroy the switching IC
inside the unit!
When you connect the correct battery, the LED immediately glows green.
By default the voltage monitor is set up for use with LiPo cells.
If you wish to use an NC or NiMH battery, you must first re-set the voltage monitor circuit,
otherwise the unit will detect the wrong battery type, and the LED will constantly flash red.
