Congratulaons for choosing the Booma RC Micro (Mikey) Switch.
Micro Switch was designed as a general purpose opcally isolated
switch for use in giant scale RC and robocs. One of the key design
criteria was to keep Micro Switch light, small and aordable.
Before you install Micro Switch please take the me
to read these instrucons. A few simple steps will
have you successfully using this highly versale prod-
uct in no me at all.
Micro Switch Features:
- Microprocessor control - of Opcal Isolated digital switching circuit.
- Fail Safe Switching - follows fail safe switching of receiver.
- High Bright Blue LED on OUTPUT - for easy daylight viewing.
- Remote Operaon - via transmier.
- Micro-Power design less than 1uA in standby mode. Less drain on your
model’s power supply so you can leave Micro Switch connected to the
baery permanently.
- Baery Input Voltage 1v DC to 15v DC. (AC version available by special
order).
- Weight 14 grams.
- Dimensions approximately 33mm x 16mm x 10mm.
Typical Usage
- Ignion switch.
- Bomb door switch.
- Navigaon Lights Switching.
- System Kill switch.
- Glow Driver Switch.
- Sck controlled Idle switch.

Lets get started
Connect Micro Switch as shown above.
Micro Switch ‘s microprocessor draws it’s power from your re-
ceiver and is only in awake state while your receiver is switched
on. Switching o power to your receiver will put Micro Switch to
sleep and remove the power to the load.
PLEASE NOTE: One of the safety features is that Micro Switch
draws it’s power from your models’ receiver so Micro Switch is
completely inoperable unless connected to your model’s receiver
and the receiver is powered up!

Micro Switch also requires one receiver channel to operate
and is set to switch at approximately 50% of sck posion. It is
recommended to connect Micro Switch to a switch channel on
your receiver and adjust the switch unl Micro Switch operates
as required. Seng up a transmier for switching will dier for
each transmier type so please refer to your transmier manual
for switch channel seng.
FOR THE TECHNICALLY MINDED ONLY
Micro Switch has a dead-band where neither an On or O state
is acve. This funconality is built into Micro Switch so that
Switch uer cannot happen.
Also, a bad signal (no pulse or less than 50% mark space rao)
must be present for more than 20 connuous frames before
Micro Switch will switch on or o. In most modern receivers fail
safe is built in so this condion should never be met except as a
complete system safety feature.
This dead band feature comes at a cost of a small delay (approxi-
mately 500 - 600 milliseconds) in switching ON/OFF.
PLEASE NOTE
Please observe correct connecon polarity i.e. RED is baery
posive and BLACK is baery negave.
An Incorrect polarity connecng will not allow your baery to
supply power to the Ignion.
Turning Micro Switch ON
Aer connecng Micro Switch to the models receiver and a bat-
tery or power to the baery input (as shown on page 4) turn on
the model’s receiver. If you have adjusted your receiver channel
correctly, switching on the selected transmier switch/channel
will arm Micro Switch and the LED will be permanently lit.
If the blue LED does not light up then you will need to adjust
your transmier. Please refer to your transmier instrucon
manual. Also please note a baery (power) must be connected
to the micro Switch baery input before the blue indicator LED
will light up.
HINT test Micro Switch’s operaon by using a sck channel
(moving the sck up down or le right) to verify Micro Switch’s
arming funcon (Blue LED permanently On) and then once sas-
ed all is well move Micro Switch to a switch channel on your
models receiver.
Turning Micro Switch OFF
To turn Micro Switch o simply move the transmier switch to
the opposite posion. The Blue LED light will exnguish indicat-
ing that power is disconnected from the load.

FACTS
Why does Micro Switch turn OFF when I switch to a turn on con-
dion via my transmier? Micro Switch is designed to switch on
from a pulse width greater that 50%. Reverse the switch condion
on your transmier will set it right.
Can I use Micro Switch as a General Purpose Opcally Isolated
switch? Yes you can, Micro Switch can be used for any general
purpose funcon as long as the maximum recommended volt-
age (12V) and current draw (4A or 6A depending on model ) is
observed.
Current carrying capacity of connectors - Micro Switch will handle
up to 4A current on the baery circuit so a JR type connector is
adequate for most uses. If a higher current rang is required we
also oer Micro Switch in a 6A version with Ultra connectors. Cur-
rent capacity will then be limited to Micro Switch design.
Using Micro Switch with a voltage regulator - Micro Switch was
designed to work with all current RC products regulated and un-
regulated. If you prefer using LifeP04 chemistry baeries (nominal
6.4v) then Micro Switch will work excellently in most RC Ignion
applicaons without a regulator.
If you prefer to use newer higher 7.2 volt servos then we recom-
mend using Micro Switch with Lion (nominal 8.2v) or Lipo baer-
ies (nominal 8.4v).
