Trevor. Something like this. What do you think. Looks like 2 regular switches with no levers.

That is exactly how you build it. Those two switches are called Snap or leaver micro switches.

AHHHH! Yes . That looks like something I can do. Is there a spring there somewhere? Cause you have to pull first right?

THKS Mike

Correct. a Bolt through the leaver with elongated holes to allow the slide action, with a spring behind it.

Works like a charm.

Make sure when you order ask for the catalog.

When you call Mouser they will ask for your customer number. Since you are new, they will assign you one.

Afterwards it's a simple matter to have your part numbers together and make the call. It's very straightforward. They have a tech line too so you can speak to a tech about your application for a particular product.

The order taker will send you to the tech line, and then the tech will send you back to the order desk.

Switches come in a variety of configurations. As an example, the fire handle switches are an 8-pole, single throw type. That means it can control eight circuits at once in an on-off configuration.

For a lot of sim building you'll want at least a double-pole, single throw. You can control two circuits with this switch. One side of the switch for signal to the input card, and maybe the other side of the switch to illuminate an indicator from a voltage source.

Some of these abbreviations you will see in the catalog are:

SPST- Single-pole, single throw. One circuit, on & off.

DPST-Double pole, single throw. Two circuits, on & off.

DPDT- Double-pole, double throw. Two circuits, on-off-on.

DPDT- Same as above, but can be ON-ON. Useful for some cards that do not recognize the off, or open state of a switch. Many keyboard encoders fall into this catagory. They need to see the keypress when the switch is thrown to ON, and they need to see it when it is thrown to OFF for the second keystroke. Landing lights are a good example of this switch's use.

SP3T or DP3T- Single or douple pole, ON-ON-ON.

There are also momentary variations of all of these switches.

The one I mentioned in my sim is an 8PST. There are many others that fall between these two extremes. Many of the toggle switches in my overhead are a 4PST or 4PDT.

The one in my glareshield rack is by far the largest switch I've ever seen. 24 contacts on that bad boy.

Excellent Trevor. I can do this. I will work on it this weeken and hopefully get some pics.

One again. Thanks Mike

Be careful. And most of all have fun with it.

Most interfaces only need one switch, which is either on or off. Here is a picture of my u-c lever for the Airbus, but all the same principle.

That is very true if you are using LED's powered from the board.

For 28VDC you need a DP switch. One side for signal, one side for power if it is supposed to light a lamp.

Thks Brian. Great work.
