Reviews
Good switch, as it should be for 4x the price of similar. Option for open/momentary closed or closed/ momentary open
This PTT is exactly what I have been looking for! It fits perfectly in a PA-28 yoke. And the snap action of the switch is reassuring. I am ordering a second one to replace the 6-months old copilot PTT
Works great!
Dont waste your time with the cheaper buttons. you will be pulling them out in a few years and installing one of these which will last forever.
Excellent push to talk momentary switch with positive detention and solid construction. Replaces most push to talk applications.
This is a real switch! It feels awesome and it is a snap switch. This means that with only a little pressure, the switch snaps closed and you dont need to mash it down to force contact. It feels amazing! Best addition.
Great PTT switch. After repeated failures of the $6 switch I tried this one. Too early to know what the life will be, but really like the positive feel of this switch.
Great push to talk switch with excellent tactile feel. Has a nice detent when the switch is fully depressed. Note that there are 3 terminal legs so you can configure it to push to close the circuit (most cases) or push to open depending on which leads you use.
This is a great switch as it pushes either to open circuit or closed circuit. I use then for things like push to talk, auto pilot disconnect and TOGA (take off and go around) . I love the small size and tactile feel when pushing. The only reason i didnt give the review 5 stars is that with one exception, in all of the switches i use/have used the little back hat on the top of the switch eventually falls off.
Feels like a quality switch. Installed in my EAB stick as a push-to-talk Switch. Has a positive Click. Last 2 cheap switches failed. 4 stars only because I dont know from experience how long it will last.

The difference is that P/N# 11-03909 is RoHS compliant when MPS-103F is not.
