Zen Toolworks (TM) Mushroom Emergency Stop Switch

Mushroom style emergency stop switch. When the switch is armed, the switch's normally closed contacts are closed and its normally open contacts are open. When the switch is pushed, the switch's normally closed contacts open and its normally open contacts close. The contacts remain in this condition until the push button is manually rearmed. Twist the mushroom button to manually rearm. The switch can be used with CNC machine control board, either shut off the main power or send a emergency stop signal to the controll software, such as Mach3. 5/8 inch Mount Hole.
