Which Switch?!

I need a switch for the electronics in my 4" V2 nosecone. Originally I looked at push on/off but having read about reliability issues with this type of switch I am now thinking of a rotary switch I can turn on with a very small flathead screwdriver.

Could you guys please post pics/links to your rotary switches? I can't seem to find anything suitable anywhere on the web.

Thanks!!

I used this switch for my L2, on several recommendations from other flyers.

I've been using twist and tape method , I have a couple of these tempted to use one on 3" build

For my latest built I decided to forget about the cost and go with these

+1 on the Featherweight mag switches. I also use them in nose cone AV bays.

RightWing,

Can you explain how this switch is mounted and activated please, a pic of it mounted would be awesome.

Where did you purchase it?

You can get them here:

You can mount it near the edge of your av-bay sled, and activate it at the pad by passing a small magnet within about an inch of the switch. No holes are required in your airframe. The mounting holes can be used to make the power connections either by soldering or by wrapping the wire under the mounting screw head.

So as much as I like the featherweight altimeter, the price for postage to the UK is more than the switch itself. So back to searching for a rotary, I can't seem to find the same style over here as you guys in the States have.

Adrian - thanks for the quick reply to my email!

Search for a Schurter 0033.4501. Farnell shows they can get it, and I know companies like Digi-key and Mouser will ship to the UK.

Thanks. I have never seen it referred to as a voltage selector! Found plenty now.

Do these switches have any issues with Mach or do you have any information on the limits?

I like the switch where you twist the bare wires together and tape it to the side of the rocket.

They're solid-state, so no issues with supersonic speeds or vibration. They will allow a few micro-Amps of current even when off, which means that you should disconnect the battery if you're storing it for more than a week or two. What type of limits are you referring to?

Simply trying to gauge why everyone does not use these, except for the obvious price, otherwise they seem like the perfect solution! I was hoping for users of them to let me know if they have had one fail if so what the failure was attributed to.
