The P1 is a sealed, dustproof, snap action, military grade switch ideal for switching low level up to 10 amps. It features screw terminals, and includes screws, lockwashers, and solder lugs.
MIL qualified. Dustproof, snap action, screw terminals, rugged reliable construction.
Excellent quality. Love that there is positive feedback when switch is pushed. It requires a bit more push than the old switch, but not bothersome. Wish the attachment had slightly larger screws and connectors. Instead, we soldered the wires to the two terminals.
LOVE em! Perfect feel for a com PTT switch.
This PTT is really high quality but way too large to install without modifying a standard yoke. I really wish this company would stock normal-sized PTTs. I know some planes are setup, but just beware that this will not fit a standard PA28/172 yoke. Spruce removed the old PTTs so now all that are left are these and sub-micro ones...
Bought for my Rans s9 Chaos and seems to work as advertised.
Perfect PTT switch for my application. Just the right pressure to activate & a positive feel engagement.
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.
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.
The diameter size of the button press fit body is 9/16"(.562") 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.
