This is my first post - greetings to all!
If you have a Jandy JVA2440 automatic valve actuator (or similar Jandy model) and you have a failed microswitch (the valve won't move in one direction, or perhaps over-rotates), and you've looked at replacing the microswitch, you were shocked like I was when an Amaz*n vendor wanted $35 for a two-buck microswitch. I looked up the Omron replacement microswitch, available widely for <$2.
The specifics:
Original microswitch: Johnson XCGS-J1Z1 (this part is $35 on Amaz*n, or only $1.53 each, if you order 2000 - yikes)
Exact replacement: Omron SS-5GLT (now we're talking; ~$1.50 plus shipping on-line; I recommend dealing with a real parts supplier, like Mouser)
A few notes on the replacement procedure:
* disconnect power
* remove the external handle and plastic bolt
* remove the 4 phillips-head screws and work the top of the JVA off (it is a little snug)
* locate the microswitches (you will replace one or both)
To replace the microswitch:
* make note of the microswitch's orientation
* unscrew the two phillips-head screws from the top of the microswitch and release the cover from the switch cradle
* remove the microswitch from the cradle (it is a tight fit)
* remove the electrical contact lugs from the old microswitch (noting that they are probably on the outermost two contacts, NC)
* replace the lugs on the new microswitch
* replace the microswitch in the cradle (this takes a little care and thumb-force, but it will go back in)
* replace the microswitch cover on the cradle with the two phillips-head screws
Now, put back on the top of the JVA and you should be good to go.
BTW, I have 4 spare Omron microswitches, just enough for a pair of JVA valves. PM me if you need some.
Regards to all,
Willie
