Schneider Electric Push Button Head, 28.5mm Push Button Diameter, Red Mushroom Head - Harmony XB4 Series - ZB4BW643
Quick action is essential in an emergency – which is where this push button head from Schneider Electric comes in. It's bright red and illuminated, so it's easy to spot when there's a hazard and you need to switch off industrial equipment immediately. For added security, the unit has latching actuation, so it stays in position and machinery remains off until you reset it by pulling it back out. With a standard cutout diameter of 22mm and screw clamp terminals, this push button head is simple to install and remove. The bezel is made from durable chromium-plated metal, which shrugs off abrasion and resists corrosion.
