Missile Works rotary swich

[solid_fuel]

I am trying to set up the Missile Works RRC2+ with the rotary switch sold by Missile Works. I think it a Schurter switch. The switch has four prongs on the bottom labeled 1,2,3,4. I have searched for about 2 hours now trying to find what wires go to what prongs on the switch for a simple on of operation, can anybody here point me in the right direction?

Thanks

I would have to go pull out my avbay. But the easiest way is to put a multimeter on there and check for continuity on the pins.


I am using the two middle pins.

Just to clarify. Do I run the negative wire directly from the battery to the Altimeter and then switch only the positive wire? And only two of the prongs get used. Two are left unused?

Switch just the positive side. Use both switches in parallel as shown.

Some altimeters have separate terminals for the battery and for the switch.

What does use both switches in parallel as shown mean?

 

[jsdemar]

Follow the wiring diagram where the top two terminals are connected together and the side two are connected together. Connect your positive battery lead to one pair and connect your positive terminal on your altimeter to the other pair. Negative battery terminal goes directly to altimeter ground or neg terminal.

This creates two switches in parallel in case one fails.

Ah. Now it’s starting to make sense. I think. I will process this in the morning. Thanks.

Neat idea using a dpdt switch for it's built-in redundancy.
