Windlass Air Switches

[Jean]

In my new (to me) Nauticat 37, one of the deck air switches is not working. I have established that the deck pad and connecting tube are fine, and that there is no fault with the wiring or main relay. When the output terminals on the switch are shorted, the main relay kicks in.
I attach a picture of the two switches, of which it is the left one (the more difficult to get at!) is faulty. Can anyone advise me (1) how to remove the switch and whether this can be done without taking out the whole panel, and (2) what is the correct Herga part number for a replacement. Any help gratefully accepted.

Hi Jean
I had similar trouble on my 37. It doesn’t work just when you need it to!! In the end I replaced the air pressure switches and now its all electric and have had no trouble since.
