MINIATURE MOMENTARY PUSHBUTTON
Works perfectly. Nice easy switch doesn’t take much pressure.
Seems to work well. Handled the heat of soldering just fine. Would prefer a star or lock washer under the nut to address vibration induced failure.
A good switch, but keep in mind it is really subminiture small.
The switch is probably ok, but I cannot use it because of its small size. The descriptions on you web site were not helpful in selecting a proper replacement switch. I ended up ordering another switch from another supplier.
Far too small for replacing the PTT switch on my PA28. Even if it worked, the switch itself is so small I think it would dig into my finger and quickly become uncomfortable to use.
They are so small I was unable to use them on my new Avion cessna182 yokes

Yes this switch button can be used on 12 volt and 24 volt systems.
Yes.
Please see the Drawing tab for measurements of the switch.
No, it does not.
The data sheet calls for a 8-40 nut.
This would require soldering the wire. There is no connector made for this.
These switches are not certified on their own. They are commonly used in aircraft and may be approved as replacements under the airframe approval. It is always wise to consult with an A&P before installing any part on a certified aircraft.
