David Clark is a high quality product. Over the years something you can count on being what you order. throughout their line of products from a simple push to talk switch. To insinuating headset.

Good build quality, these units seem to go on forever. I’ve had numerous other push to talks with them failing at the worst time. Only reason ordering these is I gave my back up to a trainee that had a failed PTT. David Clark works as advertised consistently. Did have to solder a wire in plug to make the VOX work so that is why 4 out of 5 stars. And as always Aircraft Spruce was lightning fast on the shipping.

Purchased this for right yoke. DC PTT was in bird when purchased. It is reliable and well made. I knew I could depend on its function. Improvements: reduce button box size and make button smaller.

Purchased to replace existing PTT switch, however the David Clark PTT switch does not work for my installation.
