The Opto Isolated Ignition Switch has been designed specifically for model aircraft petrol engines with ignition system. This unit will allow you to stop the engine from you radio transmitter. The unit uses an Opto Isolator which prevents the ignition noise getting into you radio receiver and causing inference. The unit is also solid state, using a power F.E.T’s to switch the ignition supply.
- Opto Isolation of the switched item to prevent interference
- Power F.E.T switched output
- L.E.D to display the state of the switch unit
- In built failsafe for P.P.M radio
INSTRUCTIONS FOR USE
Plug the servo lead in to any spare channel (normally the gear channel), but any spare channel will do.
In operation you will find that the Opto Isolated Ignition Switch will operate around the middle position on a stick channel and is fitted with an indicator L.E.D to tell you when it is on.
Plug the battery that you are going to use to power your ignition system into the socket lead and then plug the plug lead with just red and black leads into your ignition unit.
When using the Opto Isolated Ignition Switch with P.C.M or 2.4G radio it is suggest that you set a failsfe to turn the switch unit to the off state, this will kill the engine. When used with P.P.M radio the switch unit automatically stops the engine and start flashing the L.E.D.
