Greetings good people!
I have a simple circuit that uses a 12v DC wall socket adapter to power a Mac valve operating at 6 watts. Power switching is done through a mechanical air pressure sensing switch from AirTrol with a Cherry switch inside. This works fine. The only odd behavior in the system is an occasional chattering, rapid-fire on-off-on-off-on cycle that happens when the pressure switch gets near the shut-off level. I can fix this with a pressure damper in the air sensing line.
I recently put a 12v LED rocker switch in the circuit and the LED burns out after a day or so of use. Seems to happen when the system does the ratta-tat-tat on/off cycle. I checked the voltage on the power adapter and it's fine. I've replaced the switch 6 times in a week thinking at first that this was just a bad switch issue. But now I've tried 6 different switches from 3 different manufacturers.
Any ideas how to save the LED?
