This article is a so-called emergency stop switch for use in machine tools, automatic machines or the like, and is used as a switch to be pressed in an emergency to immediately stop a machine in operation. Once it is depressed, the depressed state will be maintained; therefore, in order to cancel the depressed state, a pull-up operation needs to be performed by rotating the button in the direction of an arrow on the top surface.

The broken lines in FIG. 3 drawing view depict a portion of the push button switch that form no part of the claimed design.
