E-Stop Button
 
What is it for? 
The E-Stop Buttons have the function of stopping the machine as quickly as possible in the event of an emergency. This device will be installed on machines with an electric or pneumatic action.
This feature is important for the safety of all machine operators. The feature is required by inspectors in all industries. This is extremely helpful during accidental overfills by just pressing the button and the machine will immediately come to a stop. When you are ready to continue turn the knob clockwise and you are ready to go.
