Selection Notes
Two green NO buttons marked I and II with a central red STOP suit a two-speed or two-direction start control (for example low/high or forward/reverse) that still needs a dedicated stop in the same 22.5 mm cut-out, unlike the single-NO-pair XB4BA711237 sibling built for a jog-and-stop function. Wire the STOP head to the 1 NC contact for a fail-safe stop circuit, with the I and II buttons carrying the 2 NO start commands.
