Operator Accessories

Pilla operator accessories are the add-on components required to complete every push button, break glass, and wall plate operator station. All Pilla stations ship as an enclosure and operator assembly only — contact blocks, covers, guards, and lenses are ordered separately to match your specific circuit and installation requirements.

ZOT Supply stocks the full Pilla accessories line as an authorized distributor. Whether you are building out a new installation, expanding an existing station with additional contact blocks, or replacing worn components, every accessory in this category is designed and rated to work directly with Pilla operator stations.

Not sure what you need?

Every Pilla station ships without contact blocks — you add them based on how many switching circuits your control system requires. Standard installations typically use 1 N.C. contact block (PILNCCB) wired in series with the boiler, HVAC unit, or fuel valve control circuit. Add a second N.O. block (PILNOCB) if you need a separate alarm or monitoring circuit. For 20A motor or high-current applications, specify the MDY station and MDY-rated contact blocks.
