How can I build an Altium Designer rule that applies to only one component or reference designatorrefdes?
I tried selecting my component, S1, from the Query Helper, but that just puts the string 'S1' into the query. What else belongs there?
It's InComponent(), i.e.:
InComponent ('J2') OR InComponent('J3') OR InComponent ('J4') OR InComponent ('J5')
Likewise, if you end up making a ComponentClass, it's InComponentClass():
Remember that if you do a positional re-annotation or something similar at the end that changes reference designators, your rules and component classes won't update automatically.
