Original Press Release:
High Reliability Emergency Stop Pushbutton Switches
APEM's A01 Series emergency stop pushbutton switches are designed for use in machinery where fast dependable power shutdown is essential to prevent serious hazard to the operator, or serious damage to the machine itself, or to things that come into contact with the machine.
An emergency stop switch is located in a prominent position close to the operators station, so that if a problem occurs, or is even suspected, the operator merely pushes the large red button on the switch, and power is shut down instantly breaking 2 pairs of switch contacts. This double break opens both sides of the power line for maximum safety and reliability.
To re-establish power to the machine after the problem has been found and eliminated, the switch button is rotated in the direction of the engraved arrows which re-connects the switch contacts and returns the actuator button to its higher ON position.
