EXCELLENT repair kit. Everything we needed to repair our ignition switch, including the grease, at a very reasonable price.

Nice option to replacing the complete switch every 2000 hours! Adding the grease is a nice upgrade.

Just installed the switch parts to repair a 40 year old Gerdes A-510-10 switch. Perfect fit and a 10 minute install in the old switch housing. Now I have reliable magneto grounding again. Have two #6 star lock washers for the mounting screws handy as mine broke when removing the old switch base.

ACS REPAIR KIT EXCELLENT. Did not realize that the diode came with the kit and ordered a separate one. Received the back order items a short time later. All items as ordered. Thank you.

The kit received had all that was required to complete the job, worked as advertised. Service from Aircraft Spruce was great!

Everything you need is included. Reuse the 3 springs under the triangular contacts. Rebuilt switch will be as good as new and this is an inexpensive way to avoid buying a new switch, if you think you need one.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: What do I order to prevent the ignition key to be removed before reaching the OFF position? I have a Cessna 152 with the optional 125 horsepower lycoming engine with slick mags.

The ACS ignition switches will not release the key unless in the OFF position.

Q: Is this ACS Ignition Switch service kit ok for use on certified aircraft?

Per our tech: As long as it is being installed on an ACS Products ignition switch, it will be fine.

Q: Can this kit be used to repair Bendix switches?

The A-3650-2 service kit was designed for the ACS Products ignition switches.

Q: Does the jumper for terminal 1 come with this ACS Ignition Switch Service kit?

No, the jumper for terminal 1 does not come with this kit.

Q: Does this ACS ignition switch service kit fit on a A-510-5 with no starter? If yes, can it add starter position to A-510-5?

Per Vendor: No for both questions. The A-3650-2 (11-03654) is for the A-510-2 (11-03170) only and will not give them the start function. There are other internal parts that are different as well.

Q: Is this the same physical size / dimensions as the TCM (Bendix) switch?

This (part # 11-03654) is a service kit not a switch. The ACS and TCM switches are similar in size but not the exact same size and dims.
