Note: Switches include set of 2 keys. Extra blank keys will need to be ordered separately. See "Accessories" tab.
These fine quality switches are being used in many aircraft. They provide "on" and "off" electrical control of both magnetos on single engine aircraft. The key-operated switches mount from rear of panel in 7/8" dia. hole. Available with or without starter position.
With Starter Position. Supplied w/switch plate two keys. (diode included) A-510-2
Is it possible to get the connection diagram for the terminals on the back of the A510-2? I want to connect my Hobbs meter to it so Hobbs meter only runs when Master *and* ignition are both on. Is this possible with the A510-2?
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.
what is the AMP rating?
This switch (11-03170) is rated at 2 amps in a 12V system, or 1 amp in a 24V system.
Can you please tell me what hole size ACS Keyed Ignition Switch? I'm planning my panel and trying to judge space.
The hole size that it will take up is a 3/4" hole. Now, the Switch Housing (the body behind the panel) would be 1 3/4" in diameter.
Does the jumper for terminal 1 come with the switch?
Yes, there is a jumper cable included with P/N# 11-03170 switch.
What is the start function contact ratings? What is maximum voltage?
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.
