Frequently asked questions

What does 'latching' mean for the Allen Bradley 800FM-KM21 key switch?

A 'latching' or maintained action means the switch stays in the position you set it to (e.g., ON or OFF) until you physically move it to another position. This is different from momentary switches that only activate while being held.
