Telemecanique XB4BW3335 Pushbutton Illuminated Switch

Description:

The Telemecanique XB4BW3335 is a 22 mm illuminated green flush pushbutton with spring return, an integral 6 V transformer, and one normally open plus one normally closed contact, designed for operator control and status indication in industrial automation systems. Commonly installed on control panels, motor control centers, packaging machinery, conveyor systems, machine tools, and process equipment where illuminated momentary pushbutton operation is required. Maintenance teams, OEMs, and system integrators use this pushbutton for replacement, retrofit, and new industrial control panel assemblies requiring reliable operator input and visual indication.

Applications:

The Telemecanique XB4BW3335 provides illuminated momentary control for machine start, process control, and operator command functions while using an integral transformer to supply a 6 V incandescent lamp. It is widely used in manufacturing plants, material handling equipment, HVAC systems, water treatment facilities, packaging machinery, and OEM industrial automation panels.
