Push Button Stations

Pilla push button operator stations are UL Listed, NEMA 4/4X/12 rated emergency shut-down stations built around a 40mm red mushroom operator in a surface-mount yellow enclosure with bold luminous legends. Every station ships as an enclosure and operator assembly — contact blocks are ordered separately and stacked to match your circuit requirements. ZOT Supply is an authorized Pilla distributor stocking the full push button line including boiler shut-down, HVAC shut-down, fuel shut-off, generator stop, and general emergency shut-down series.
