Schneider Electric Yellow Mushroom Pushbutton Head, Panel Mount, 22mm Cutout - Harmony XB4 Series - ZB4BS55

Use this pushbutton head from Schneider Electric to control your machine-operated processes and promote workplace safety. This device can't be pushed to activate operations until it's turned clockwise, which makes it safe to use with dangerous machinery. The bright yellow colour makes it highly visible and easy to locate, enabling staff to quickly stop workflows. Latching actuation keeps the pushbutton in the selected position until you change it, meaning it prevents accidents, injuries and damage to valuable equipment.

• Sustainable product that's environmentally friendly and easy to recycle

• Operating temperature range between -40°C and +70°C for use in extreme conditions

• Resistant to vibrations and impact for durability in tough industrial and commercial environments

Applications

• Manufacturing

• Laboratories

• Automotive engineering

Can I use this pushbutton head outdoors?

Yes – this pushbutton head has an ingress protection rating of IP69K, which means it's protected from dust and high-pressure water spray from any direction. Its chromium-plated bezel is hardwearing and resistant to corrosion, meaning you can safely use this unit outdoors.
