MIL qualified. Dustproof, snap action, screw terminals, rugged reliable construction.
I decided to try these in my PA-38 because I use it for training and my students wear out other PTT switches quickly. They fit nicely and so far are working very well. They feel very solid and durable. The 4lb. pressure works out great since students tend to push hard on the switches.
Bought the switch when chasing a problem that turned out to be a bad wire not a faulty switch. But I like the feel of this one with the positive click and the larger style.
Product was what expected. One good reason I use Aircraft Spruce is the website is user friendly .
This is a high quality switch with an aluminum bezel. It takes a relatively good force to press. I understand the rating is a 4lb force to depress. It would be nice to have the option to purchase the 2lb force made by the same company.
The switch is of good quality but much too large to fit into the yoke horn as a PTT.
Solidly built and should provide years of service. The switch trigger pressure at 4 lbs is greater than my old switch but I quickly adjusted to it. The switch also provides tactile feedback of a solid click when pressed.
Just installed it, did not need all the hardware but just used the boot that came with the old PTT. Much better quality than the old one, very solid. Ill be buying a second one soon.
best PTT Ive found. high quality w/ larger than normal push button(nice).
A quality switch with a nice click action. The body is made from powder coated aluminum and not plastic like it looks like.
The diameter size of the button press fit body is 1/2in and the button is red while the body is black.
Momentary means you have to hold the switch down to activate it. As soon as you release the switch it turns off. Press fit means that there are no threads and simply pushes into an exact size hole. SPDT means single pole double throw. This is a switch that only has a single input and can connect to and switch between 2 outputs.
No, this switch can be wired in either direction.
The switch has screw terminals. Included with the switch are screws, lockwashers, and solder lugs.
Yes, this requires a 5/8 mounting hole.
No, this should work fine in a 14 volt system.
