Even more from Honda. Buy once, cry once. The price hurts once and then, after that, when you're not still fixing it, you're enjoying it. Just buy the right part, from the right place, and repair it once and be done.
Most people don't actually diagnose the failure and conclude with 100% accuracy that it's the switch itself, or the solenoid, or something else. If you're 100% sure the switch itself is bad, it's not leaking, and you have no other issues, then I'd probably do it. When vehicles have both a front and rear spool valve I've been known to swap them to confirm. However, with them leaking so often and the gaskets not being available (the aftermarket ones that are available don't last) it's best to just replace the entire valve assembly and be done.
