Frequently asked questions

What is the difference between twist-to-release and twist-to-reset for Allen Bradley 800H push buttons?

Both are safety mechanisms for emergency stops. 'Twist-to-release' and 'twist-to-reset' refer to the same function: the button latches when pressed and is reset by twisting it. The specific nomenclature may vary, but the operational principle is identical for safety purposes.
