DPDT on-off-mom switch source?

[Junglepilot]

Its hard to believe but I am having a hard time finding a DPDT on-off-momentary switch for my flaps. I have an "on-off-on" and "mom-off-mom". Not what I need.

Built single circuit board with [10a-800v] diode for up limit and zeners for the spike protection feature on a perf board.

I want to command full up/on a flick for go-arounds, etc., and momentary feature for bumping down.

If someone has a good aviation grade source (AN or MS) it would be appreciated.

I think you want the S700-2-5. I have two of them in my panel.

The APEM 648NH/2 is the one we used for flaps. Available through Digikey.

I'm pretty sure I have 2 of these that I never used that came with the Vans flap system or the safety trim system I would be willing to part with. (I used the infinity grip instead). Shoot me a PM or email if interested...

Check out the S339T at:
http://www.nkkswitches.com/pdf/stogglesmedhighcap.pdf
TCW Includes the S309T (SPDT version) with their safety trim system, and Vans or Showplanes include this same switch with their electric flap system. That's why I have 2 of them. I thought they were DPDT but they are single pole.

The DPDT version is available from Mouser for $9.54:

Good Luck!

Thanks,

Good switches and they all have a DC rating quoted of 20 to 25 amps...

Hi Guys,

Can you recommend On-Off-Mom switch function that is a pushbutton type?

I've been looking all over and I cant find this type of switch I can found rocker or toggle switch only.

I'm just wondering if this is existing on a pushbutton type.

BR,

Jay

If it exists it would be very rare.

It would be a three push action, and how would the (MOM) push cycle work? It would just take you to the next state...

 

[jaycarlo29]

So you mean this is rare switch and I its not recommended.
Can you recommend one.

Basically, I need a switch for Turn On and Off the device.

The third function is for updating the firmware so that user won't open the casing just to do that.

If you can recommend other better way without any complex circuit would be great.

Here is one from Aerosport Products:

Basically I want a switch like used in the desktop.
When pressed short duration it will turn "On", when pressed for more than 3 sec it will turn off. Something like that.

Switch with 3 function, but the third function is hidden so that the user wont accidentally misused it.

Jay, the action you're looking for isn't a part of the switch on a desktop computer... The switch on most modern desktops is just a momentary push button, and there is a circuit on the PCB that it connects to that takes care of the logic.
