Note: Switches include set of 2 keys. Extra blank keys will need to be ordered separately. See "Accessories" tab.
These fine quality switches are used in many aircraft. The switch housing is now machined from billet aluminum which makes this switch 25% lighter. They provide “ON” and “OFF” electrical control of both magnetos on single engine aircraft. The Key-operated switches mount from the rear of the panel in a 7/8” dia hole. Available with or without starter position.
With Starter Position. Supplied w/switch plate two keys. (diode included) A-510-2
FAA PMA Approved.
Made in USA
Much better construction and operation than the Bendix/TCM switch at less than half the cost. My starter was slowing. The Bendix switch was the culprit.
Works as it should. Decent price as far as aviation parts go. They always have these in stock as well.
This switch sooo much better than the switch that was in my 46 Stinson. Operates smoothly and easily.
The screws provided are very short and when you have to place multiple terminal ends on one connection (ground wire and 2 shielded wires from the P leads onto the 1 ground stud) they are inadequate. If we had not had longer screws leftover from a previous install (from a Bendix unit) wed have had an issue completing the installation. Performance of the switch is as expected with very positive yet smooth movement from Both to Left and Right mag positions when accomplishing a mag check.
Just what I needed for my panel. I like the all in one simplicity.
The right part arrived on time and works as represented. Cant ask for more than that.
Please see the Documents tab of this web page. There is a link to the "Installation Diagram". This will provide all available terminal connection information for this ACS keyed ignition switch.
This switch (11-03170) is rated at 2 amps in a 12V system, or 1 amp in a 24V system.
Yes, there is a jumper cable included with P/N# 11-03170 switch.
Momentary "on" function on "start" (spring-return to "both"). Current through "BAT" & "S" terminals is 2 amps inductive at 12 volts or 1 amp inductive at 24 volts. Current through "L" and "R" magneto grounding circuits is less than 0.5 amps. Open circuit voltage is 300 volts.
The O.D. of the threads are approx. 7/8", but you will want to have a notch in the hole so the switch does not rotate. The drawing is in the documents tab.
1 year manufacturer's warranty.
This is 2.28" length and 2.23" at its widest point.
Approx .209 lbs.
In the left position the right mag is grounded and in the right position the left mag is grounded.
You will need a stud size #6 for the ring terminal to be used on Part # 11-03170.
