Product description

The Allen Bradley 800H-QRH2A is a 30.5mm maintained push button operator with a red lens. Unlike momentary buttons, this type stays in the activated position until it is pressed again, making it suitable for control functions that require a persistent state.

This maintained push button is widely used in industrial settings for applications such as emergency stops (when configured with appropriate contacts), on/off switches, or to hold a specific machine function in place. It is essential for many control panel designs in manufacturing and processing plants.

Frequently asked questions

How does the Allen Bradley 800H-QRH2A maintained push button work?

The 800H-QRH2A is a maintained push button. When pressed, it locks in the 'on' position and remains so until pressed again, at which point it releases to the 'off' position. This is ideal for functions that need to stay active without continuous pressure.
