P1 Momen. Switch P1-32121 Red
These look to be a great improvement over the micro switches that are being replaced. I really appreciated the outstanding customer service provided.
P1 Momen. Switch P1-32121 Red
Built like a tank! Should last for years. A little bigger then you might think.
P1 Momen. Switch P1-32121 Red
Excellent Built Robust Switch. I used it for a autopilot disconnect switch on a Dynon Skyview install. I like that the wires attach by screws with lock washers. It comes with everything needed to attach switch and wires.
P1 Momen. Switch P1-32121 Red
Very nice switch but turned out to be too large. Returned.
P1 Momen. Switch P1-32121 Red
Substantial “click’ when pressed lets me know it is working. Well built switch!
P1 Momen. Switch P1-32121 Red
Replaced old small push to talk switches in the yoke. This is a great replacement option however, ensure you have enough space in the yoke as these are slightly wider and taller than others. Really nice feel and look. A real pilots PTT.
P1 Momen. Switch P1-12122 Blk
I havent used the button yet, but it appears and feels very high quality, button has great snap action. The button was shipped quickly and packaged well. I would and plan to purchase more of these buttons.
P1 Momen. Switch P1-12121 Red
As expected...quality part. Includes the tiny screws as well
P1 Momen. Switch P1-32121 Red
I have not installed it yet but it appears to be heavy duty. Its not cheap, I think this push to talk is going to go the distance. For those who may from time to time be a little heavy on the button push this one if for you! I cant wait to install it as I think it will be the last PTT I ever need to put in (after I purchase another one for the back seat as well). This switch is not for the tender trigger fingered, definite not going to press this one down by accident even if you are palming the stick and its on top. No need for a safety on this one )

No, this switch can be wired in either direction.
The switch has screw terminals. Included with the switch are screws, lockwashers, and solder lugs.
