Members of the A01 series of emergency-stop pushbutton switches are designed for use in machinery where fast, dependable power shutdown is essential to prevent damage to the operator and to the machine itself. Using this switch, power is shut down instantly by breaking two pairs of switch contacts. The 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. This reconnects the switch contacts and returns the actuator button to its higher ON position. The switches fit a variety of applications, including mobile conveyances, automatic assembly machines, printing presses, radiation units, and overhead cranes. They're offered with a choice of either a 1.575- or 0.945-in. diameter and are rated from 10 mA at 5 V ac to 6 A at 250 V ac. Pricing for a typical A01 unit is $11.82 each in 1000-piece quantities.
