Shipped qty is 2 (complete set for B737)
This switch is suitable for use in any overheadpanel for the B737 series.
This switch controls the igniters that starts the engines of the B737. The real ones is extremly hard to find and are sold at very high prices when available. I decided to make a realistic replica of the real switch.
I've had real world pilots testing the switch and their feedback has been great!
The big difference to a normal rotaryswitch is that these switches have much higher requirements. First of all you will need to push the switch in to turn it from OFF position. Also the GND position is spring return with an holding coil. When the coil is energized the switch will remain in the GND position until you break the coil circuit, then the switch will pop back to OFF and pop out. You can also turn it back manually (override).
These switches features all the functions the real ones have, even the sound when the switch goes back to OFF is very similar to the real one. The big difference is the price. These switches doesn't even cost half of what you will have to pay for real ones.
When starting the engines you push and turn the knob to GND. If all parameters is correct the switch will hold in GND position and stay there until starter cutout. This is shown in the video below.
I've done a very unique design, seen at no other competitor. The switch has the exact same look as any other rotaryswitch in concern of mounting. No need to drill holes or changing anything with your overhead. Just fit them into the existing hole and tighten the lockning nut and you are ready to interface them.
I'm only using high quality parts from brands like Carling, Lorlin, Lesjofors, SKF, TDS etc. They are built to last for many years. Materials used is Aluminum and Acetal.
Guaranteed to work with:
And may also work with a lot other software as well. It really depends on your choice of electronic cards.
Required for installation:
8 digital input on your I/O-card and 2 relay output.
12VDC Power supply (You can use the same for both switches)
Diode to protect your computers from electromagnetic field generated by the coil. (INCLUDED)
Thanks to Scott for this review of my starters in-action.
