Introduction
Main Switch is an electronic switch designed primarily for switching of the main power supply for an RC
model. It adds an element of safety when handling the model, without the need to physically disconnect the
model´s batteries. A big advantage of electronic switches in comparison to mechanical switches is, in general,
their higher reliability as far as vibration resistance is concerned. Another advantage of the electronic switch is
its ability to withstand an unlimited number of switching cycles. Electronic switches have no moving parts like
contacts which would be worn out during the switching processes, therefore their longevity is extremely high.
Moreover, they are not prone to spontaneous and unexpected false tripping with known disastrous effects. Last
but not least, electronic switches offer a much lower inherent transient resistance in comparison to mechanical
switches. The Main Switch prevents the connectors from sparking when connecting the batteries, thus it can
also replace Anti Spark plugs.
The Main Switch is shipped with a magnetic switch. The magnetic switch instructions can be found on the
manufacturer´s website. It is also possible to use the optional RC Switch instead of the magnetic switch.
The Main Switch is primarily designed for switching the main power supply of the RC models, but can also
be used in applications where switching a DC power supply is needed.

Connection
The power supply is connected to the Main Switch using two input wires with cross sections of 6 or 8mm
2
.
The output voltage is available at two cables with cross sections of 6 or 8mm
2
. The output three-wire cable
with the JR connector is used for telemetry data transmission. The output three-pin connector is used to
connect the supplied magnetic switch or the RC Switch.
The Main Switch connects and disconnects the negative pole - ,
the
+
pole is always connected and is
never disconnected!
Fig. 1: Connection of input and output cables
Please take care when connecting the input and output cables, the red cables always represent plus poles and
black cables minus poles – their correct connection to plus and minus poles is of utmost importance.
PAY ATTENTION to the correct connection of the input IN and the output OUT!! In case of a
reversed connection the switch may be destroyed!!! This type of damage is NOT covered under
warranty. Only connect batteries to the input IN and connect speed controllers, receivers, servos etc. to
the output OUT.
