Allen-Bradley 800FM-E4 Extended Momentary Push Button

Allen-Bradley 800FM-E4 is a 22.5 mm metal, extended-head, red, non-illuminated momentary push button with two normally closed contacts and one normally open contact. It belongs to Rockwell Automation’s 800F family of push-buttons and is designed for panel-mounted control applications, delivering a momentary electrical signal when pressed and returning to the rest state when released. The extended head design provides extra finger clearance in tight enclosures, while the metal housing supports durability in industrial environments. This three-contact operator enables straightforward wiring for common control logic such as start/stop and interlock circuits, when used with compatible 800F contact blocks. Typical uses include control stations, reset or test actions, and other non-illuminated input points on industrial equipment.
