Product description

The Allen-Bradley 800T-QAH2R is a momentary push button featuring two Normally Closed (NC) contacts. It is part of the robust 800T series, engineered for durability and reliable performance in demanding industrial settings. The momentary nature means the contacts revert to their normal state when the button is released.

This push button is well-suited for control circuits where the primary action is to break a connection, such as in safety circuits, emergency stops (when properly integrated), or for controlling auxiliary functions. It is commonly applied in manufacturing, material handling, and process control industries.
