A 22 mm red push-button operator designed for industrial control panels, featuring a snap-fit head and metal mounting collar for secure installation
The Schneider Electric ZB4BT84 is a 22 mm chromium-plated metal push button operator built for industrial control panels and machinery. It fits a standard 22 mm cutout and uses a snap-fit head with a single-screw locking collar for fast, secure mounting. The modular design allows operators to assemble complete units from separate head, body and contact modules to match specific application requirements. Buyers needing a plastic bezel or a different colour coding will need a different series.
As a passive electromechanical operator the unit generates no heat and produces no audible noise during actuation. It draws no power itself; electrical load is determined entirely by the contact blocks chosen and the circuit it controls. The shake-proof connection screws on those contacts remove the need for periodic retightening in vibration-prone environments. Installers who require illuminated or selector-switch variants must add the appropriate modules separately.
The fully metal mounting collar and chromium-plated body resist corrosion and mechanical wear in harsh industrial settings. Accessories are available to maintain sealing against high-pressure cleaning, dust ingress and extreme temperature exposure. The single-screw fastening system simplifies panel assembly while keeping the operator firmly locked in place. Users planning to integrate the button into a custom enclosure should verify cutout dimensions and collar clearance against their own drawings.
