Selection Notes

The integral LED gives a steady indication of which position is selected without a separate pilot light, which matters in dim control rooms where a plain handle's position can be hard to read at a glance. The 24 V AC/DC rated supply suits panels standardizing on a 24 V control bus, avoiding a separate 230 V lighting circuit; choose the XB5AK123M5 variant where the panel distributes 230 V AC instead. The 1NO+1NC contact block gives a simultaneous make and break signal from one actuation for interlocked mode confirmation.
