Leburg ignition switch

Post by andypgow » Sat Nov 13, 2021 5:15 pm

Hi
Does anybody know what switch should be used for the A ignition on a Leburg ignition switch?
The manual says to use a Farnell DPDT switch part number 285-936 but this no longer exists according to their website.
From what I can gather from the Leburg wiring diagram the A switch turns off the A ignition but transfers the power to the tachometer through the B ignition .
If this is the case do I need an on on switch.
Please help
Thanks Andy

Any on/ off switch would suffice (reasonable quality) You have outputs from the modules that feed the tacho. I put in a small 3 way switch
to read each ignition ie middle off left or right as required.

Hi Mike
Thanks for your reply
Are you saying that you have each ignition module controlled by a separate on off switch and then a third switch which just controls the tachometer?

Yes very simple, and no current drain when off

Just one other point. I fitted buzzers to mine as in drawings so when switched on you get an intermittent beep🤓

1 thing I was pleased with, I made a small ignition panel that bolts onto back of instrument panel. Ie has switches buzzers and circuit breakers on it. Means you can remove instrument panel without disconnecting any wires.

I put incredibly loud piezo electric beepers on the engine side of the firewall as per the Leburg plans on our VP1.
G-BAPP had a canopy so I regarded hearing them outside with the canopy closed when hand cranking as more important than hearing them inside, but I could anyway, even with a headset on! :D
Huge 10mm LED warning lights on the dash were useful as well! I used clear LEDs that light up red - you can tell they are on even in bright sunlight!
