Ok sorry for the simple question, I have the THUMB grapple and I am going to purchase a surplus center selector valve. I have two options that I am looking at the P15544-2 / 9-5117-A SPST switch or the P15544-1 / 9-5117 with SPDT-CO.

What is the difference between a SPST and SPDT-CO as far as the operation of the Grapple?

This is going on my JD 2520.

Thanks

Davy

J J,

That answers my question for the single throw, that seems like all I would need.

Thanks
