Linear actuator spec.: 400mm stroke, 6000N, 2 limit switches, 5mm/sec, 12V DC supply, BIBUS IP65 casing. One of the limit switches of my LA (Linear Actuator) seems to have burned out. This happened because I accidentally plugged the LA leads into the AC mains socket (my LA is rated to run at 12V/24V DC). I could guess which limit switch burned-off from the way the relay erratically turned on-off everytime I reached one end of the LA. I would like to know the best way to replace the limit switch at the top-end. I've attached a pic showing the IP65 motor cover off. I want to seek advice before I take any of the motor screws off. How do I reach the limit switch at the top-end of the LA? And some tips on where I could buy a replacement limit switch would help a lot. Pics are in attachments. Thanks!
