•
Electronic safety switch harness
•
Compact design, low weight
•
SMT construction, low-wear, vibration-proof
•
High-quality gold-plated connector systems and large con-
ductor cross-sections
•
High continuous current capacity
•
Failure-proof: if a fault develops in the slide switch or its con-
necting leads, the electronic circuit ensures that the last
active switched stage (ON or OFF) is maintained. This
means: even if the switch comes adrift in flight due to
vibration, the power supply to the RC system is reliably
maintained.
•
Two receiver leads provide double the conductor cross-
section and twice the number of contacts in the case of the
SAFETY-SWITCH 12HV / 12HV TwinBatt.
•
MPX M6 high-current connector on the SAFETY-SWITCH
12HV (M6) / 12HV TwinBatt (M6) for direct connection to
MULTIPLEX RX-9/12/16-DR pro M-LINK or RX-9/12-SYNTH
DS M-PCM receivers.
•
Integral battery backer in the case of the SAFETY-SWITCH
12HV TwinBatt / 12HV TwinBatt (M6). Both batteries are
discharged simultaneously and evenly. If one battery should
fail, the second pack powers the receiving system on its own.
•
Two sensor sockets on the SAFETY-SWITCH 12HV
TwinBatt, for monitoring the voltage of both receiver batteries
in flight. This provides a more accurate method of assessing
the state of the receiver battery while the model is flying.
The switch harness is an important safety-relevant component in
the receiving system power supply chain. After a certain period of
use, conventional switch harnesses with purely mechanical
switches represent a security risk due to ageing effects such as
vibration, wear and corrosion. What is more, the demands placed
on switch harnesses are rising due to the power requirements of
modern high-performance servos. Many conventional, purely
mechanical switches are simply not up to the job.
The receiver battery or batteries are connected directly to the
SAFETY-SWITCH circuit board. The unit is connected directly to
the receiver by a short cable which features no mechanical
switch element. The switching function is carried out by
extremely reliable, vibration-proof, high-performance FETs, which
exhibit very low internal resistance compared with mechanical
switches. In conjunction with high-quality gold-contact connectors
and cables of generous cross-section it is finally possible to
exploit the full performance potential of modern servos.
A mechanical slide switch acts as the ON / OFF switch element,
but all it does is provide the ON / OFF switching signal. The load
current does not flow through this switch. The switch can be
installed in any easily accessible position in the model.

1. Mount the SAFETY-SWITCH harness in the model in a
position where it is well protected from vibration and shock.
2. SAFETY-SWITCH 6HV: connect the UNI lead (RX) to your
receiver’s battery socket.
SAFETY-SWITCH 12HV / 12HV TwinBatt: connect the
second UNI lead (RX) to any vacant servo socket on the
receiver, or - if present - the receiver’s second battery socket.
!
Note
When connecting the UNI lead(s) (RX) please take care to
maintain correct polarity; this applies in particular to the pin
assignment of other makes of equipment:
SAFETY-SWITCH 12HV (M6) / 12HV TwinBatt (M6): connect
the two-core lead (RX) terminating in an M6 socket to the M6
connector on the MULTIPLEX RX-9/12/16-DR pro M-LINK or
RX-9/12-SYNTH DS M-PCM receiver.
3. Install the mechanical ON/OFF slide-switch in any con-
venient position in the model, if possible protected from
accidental actuation.
Connect the 4 - 6 NiXX cells or 2S LiXX battery pack(s) to the
socket(s) marked “BATT” on the SAFETY-SWITCH. Take
care to maintain correct polarity:
!
Note
The basic rule is that you should only connect components to
your receiver which are designed for the voltage of the
receiver battery you are using (4 – 6 cells or 2S LiXX).
!
Note
The integral battery backer is a reliable, robust diode type
consisting of few components. The voltage drop across the
backer is around 0.5 V.
!
Note
The SAFETY-SWITCH 12HV TwinBatt should only ever be
used with two identical batteries: same type, capacity, voltage
curve, age and performance.
•
Connector system on the SAFETY-SWITCH 6 HV:
MULTIPLEX MP-RC. Matching connectors: MP-RC battery
lead (# 8 5102) or MP 3-pin socket (# 8 5225).
•
Connector system on the SAFETY-SWITCH 12HV (M6) /
12HV TwinBatt (M6): M6 plug.
Matching connector: M6 socket (# 8 5214).
4. Switch your transmitter ON, then switch your receiving
system’s power supply ON using the SAFETY-SWITCH’S
ON/OFF switching element. When switching OFF: first
operate the SAFETY-SWITCH’S ON/OFF switching element,
and only then switch the transmitter off.
!
Note
The lead to the mechanical ON/OFF slide-switch can be
extended to any length if necessary.
5. If you are using a telemetry-capable receiver and transmitter
together with one of the 12HV TwinBatt / 12HV TwinBatt (M6)
versions it is possible to connect a voltage sensor (# 8 5400)
to one of the two 2-pin UNI sockets on the circuit board; this
is accomplished by connecting the sensor lead (supplied with
the
sensor)
to
one
of
the
two
sensor
sockets
(Sensor 1 / Sensor 2). If you connect a second sensor lead
(# 8 5056) to sensor output 2 on the SAFETY-SWITCH 12HV
TwinBatt / 12HV TwinBatt (M6), you can transmit the voltage
values for both receiver batteries to the transmitter (e.g.
ROYALpro) after activating the second measuring channel;
this is carried out using a MULTImate (# 8 2094) or Sensor
DataManager.
