Schneider Electric 9001K16B Mushroom Head Pushbutton Switch

Product Description

The SCHNEIDER ELECTRIC 9001K16B is a nonilluminated extended mushroom head pushbutton switch knob designed for 30 mm industrial control operator assemblies. Made from polycarbonate, this black round snap-in knob attaches to compatible pushbutton operators to provide a large-surface, extended-profile actuator. The mushroom head format is standard in emergency-stop and process-halt applications where operators need a broad contact surface for quick actuation. Electricians and control panel technicians install this component as a replacement or new-build operator element in industrial and commercial control enclosures. At 0.09 pounds, it is a lightweight but durable accessory suited for repeated use in demanding environments.

This knob is intended for use on control panels, machine operator stations, and industrial enclosures where 30 mm pushbutton operators are specified. Its snap-in design makes field replacement straightforward without specialized tooling. The nonilluminated configuration is appropriate for applications where pilot light indication is not required at the operator position. The extended mushroom head profile is commonly selected for functions requiring easy visual identification and rapid manual actuation on the panel face.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and local codes.
