Exactly the same behavior with the second universal. These are UT-3000s, if that matters.
The EzSnsRf is Rev 1.3, Firm 52.
A bad EzSnsRf might explain the 11 followed by 13, but how to explain not getting anything from the UT-3000 when expected? I get the same behavior when using NO as when NC, except in reverse. I either get a signal when closing, or when opening, but not both.
PLEASE tell me they’re not expecting a SPDT switch. Aside from the contact bounce issue, where am I going to find a magnetic contact switch that’s not SPST?
