Selection Notes

The flush blue head and plain lens distinguish this unit from the standard non-illuminated XB4 push buttons in the same bezel: the integral LED gives a steady status indication at the operator position without a separate pilot light. The 24 V AC/DC rated supply suits machines running on a common 24 V control bus, avoiding a separate 230 V lighting circuit. Pick the 1NO+1NC contact block when the application needs a simultaneous make and break signal from one actuation, for example a start command interlocked with an indicator lamp circuit on a second PLC input.
