The emergency stop button of the roadheader USES normally closed contacts.
After pressing the emergency stop button, it can be self-locked in the disconnected state.
Only after rotation can it be reset to prevent misoperation and remove the stop state.
The emergency stop buttons are red and mushroom-shaped for easy tapping.In some cases, a cover is added to prevent accidental touches.

The emergency stop button can be pressed to stop the whole device quickly, or some transmission parts can be released immediately.
If you want to start the device again, you release the button, that is, you just rotate clockwise about 45 degrees, then release it, and the pressed part pops up.

Therefore, when designing a machine with transmission parts, add an emergency stop button.In addition,
it should be installed on the surface of the machine, easy to press, and there should be no obstacles.
