bought some allen bradley "800 type" control panel pushbutton switches.
they have seperate (screw-fastenable) rear contact blocks. I see one
type of contact block allen-bradley offers for these pushbuttons is
called a "logic reed", and wonder what it's purpose is? or how it's
supposed to function, or "what can logic reeds do for me?"

momentary offs and ons I understand, and normally offs and ons I
understand, but "what's the logic reed thing about"?

tried searching the net for this type info, unsuccessfully :-/

*thanks* guys

here's the (dirty, used) ones I bought
