The SIRIUS ACT series labeling plate is a standardized accessory label displaying I-O-II positions for identifying switch states on push button control stations. It mounts directly onto SIRIUS ACT push button switches in industrial control applications. Critical verification: confirm compatibility with the specific push button housing model and ensure label orientation matches control logic (typically I=On, O=Off, II=secondary position).
