Pico Switch RED/F5J Backup System & Magnetic Switch
Description
- Backup facility will run the RC from the highest voltage power source.
- Can be powered from 1S & 2S LiPo batteries, 4-6 cell NiMH batteries, and an ESC BEC.
- Batteries/ESC can output different voltages, the RC will be powered from the highest voltage source.
- The lower voltage battery will not be reverse charged, so 1S LiPos can be safely used as the backup battery. This will allow a battery voltage telemetry warning to tell the pilot that the system has switched to the backup battery.
- Clever firmware indicates when the switch is sensing the magnet to give instant feedback.
- When switched on the LED flashes indicating the RC is now on.
- The flashes are very brief to keep the switch's energy usage to a minimum.
- The magnetic switch utilises a Hall Effect Sensor (no mechanical switching parts).
- Safe and reliable :
- Default to on - if the battery is disconnected and then reconnected the output will turn on every time.
- The magnetic switch is programmed to ensure the magnet is over the sensor for 3 seconds without interruption and only then will it toggle the switch state.
- Extremely resilient to magnetic interference due to the algorithm used.
- Place the switch as close to the fuselage or wing surface as possible.
- Use a thin piece of double sided tape to hold the switch in place.
- To locate the sensor simply sweep over the approximate sensor location area, when the Hall effect device sees the magnet the LED will turn solid on indicating the perfect position.
- Use a marker pen and mark where the sensor is located.
- To turn the switch off place the supplied magnet over the sensor and the LED will light up continuously. Hold the magnet in place for 3 seconds without interruption. Tip: count 1, 1000, 2, 2000, 3, 3000.
- To turn on the RC hold the magnet over the sensor again, keeping it still for three seconds, as above.

Quick service from Hyperflight. I have not used the switch yet, but the previous pico switches I have used have been excellent
Bought two Pico Reds and installed in both a Prestige 2PK Pro Standard and Storm. Both in conjunction with a 2S/300 battery. My last flight yesterday testing 6S in the Storm, and not yet familiar with the total consumption used at full power. Ended up at around three hundred meters in 10 seconds (after already flying for 20 min...) and got low voltage warning. Looked at the Jeti display which told me 15 volts! No chance to fly the 2PK down in time. Then "popped" the low RX voltage up, and the backup battery took over. Full brakes from 300 meters brought the ship safely down.
I have set the BEC voltage to 8,4 V, and charged the 2S/300 battery to 3,9V cell (7,8V total). 3,9 V gives around 190 mAh for use. The telemetry is set for Voltage low at 8V, so I knew the backup was "taking over".
What a fantastic solution! It helped me this time, but I know for sure to land before this happens again
I have not used yet but looks good. Very fast delivery.
Neil was quick in sending but due to customs it took a while (Brexit). My AVA has a detachable nosecone (old lady). Now I switch on and off during a flightday without unscrewing the nosecone. Ok, I'm a bit lazy. Or in English: economical with my energy!
Very small and light i am using it on an explorer f5j as i am stretching the yge esc (bec set to 7.4v) to its limits and wanted a backup in case it fries. I have a tiny 260 mah two cell lipo and a tiny 5v 6g bec, plenty to get through a flight safely. Seems to be a good solution.
