I recently purchased a 1969 Cessna 172K. Great plane, have had fun flying it. Just recently the flap switch on the panel decided to go bad. There are several questions here. Prior to the switch going bad, it was a momentary DPDT switch both ways (Momentary On – Off – Momentary On). That of course meant you had to hold the switch in the up position to retract the flaps. First question – was that and is that the correct function of the switch?
The switch was replaced with a new switch supposedly with the same part and the new switch is only momentary in the down position which is what I would have figured it should be. However, now when you flip the switch to retract the flaps it stays in the up position after the flaps are retracted but after a few seconds, 10-15 or longer, it pops the breaker. According to Cessna prior to a certain serial number of the plane the switch and mechanism were different. Second question – can anyone explain what type of switch should be installed? My plane has the serial number before the change in mechanism. Last question – is there a limit stop in the flap motor for up and down? There are no external limit switches anywhere so it is obvious if power is still present in the motor it will eventually pop the breaker.

Thanks for any ones help.

i also have a k model and replaced the switch. the replacement switch has to be held in the down and up position.it is spring load to the off position (center). the flap motor has no limit switch so it will run as long as the flap switch is help down and up. if the motor gets hot it will pop the breaker. hope this helps.  manny

I believe that the flap actuator does have up and down limit switches. If your flaps motor continues to try to run at the full up and full down positions your switches are misadjusted or defective.

The earlier Cessnas have a center off ,hold for down and up ,flap switch. Later models have a "hold for down" and spring loaded up.    Still later models had a slotted gate for the flap switch with detents for 10,20 and 30 degrees. The switch is moved to the selected flap setting and the flaps lower to the selected setting.

The switch is outrageously priced from Cessna. Best bet is an aircraft salvage yard

Re: Cessna 172K Flap Switch and Motor problems

I have a 172K with serial 17258613 and it seems I don't have limit switches.
However, you can download the service manual from
http://www.micro-tools.net/pdf/Cessna
and it refers to limit switches in chapter 7, apparently if modifications are done.

I put in an Aircraft Spruce LED indicator, which is somewhat better than the stock indicator.
