Replaced a microswitch in one of my valve actuators.
When I opened it up it was full of water, dont know how the microswitch survived as long as it did. Motor and gears were fine, however. Took the air compressor and blew out all the water. Lubed the case, and the o-ring.
Also just for note the Hayward GVA-24 actuator takes an Omron SS-5GL13T microswitch. The only difference between that and the SS-5T is the lever. I managed to transfer the lever but not without breaking it a little. It will hold for a while, but went ahead and ordered 4 more of the 13T so I have them hanging around.
Mods, you may want to update the valve actuator wiki to help out the next person.
