SPDT switching — what it means for your control circuit
The ABB 1SVR405611R7000 is a SPDT relay — one common terminal that switches between normally-open and normally-closed contacts. This gives you a single-pole changeover: the load can be energized in one state and de-energized in the other, which is the standard building block for interlock, selector, and fail-safe circuits.
