A legend plate is a component used in conjunction with push-buttons and switches to highlight the placement of the button. They can also provide clear visual indication when the mechanism is triggered. Some rings will have text or symbol engravings on them that display what happens when you press, pull, push or twist a component. This type of ring is usually used within industrial workplace settings, where tactile emergency stop processes for potentially dangerous or expensive machinery need to be obvious, quick, and easy-to-use.

A push-button is a switch mechanism that controls a function within a machine or device, such as an instant shut down.
