- Description
The Siemens 6AV7674-1ME00-0AA0 is a 22 mm key-operated switch for front-plate mounting in the Extension Unit of a SIMATIC HMI PRO device, with 3 latching withdrawal positions and 2 keys supplied. It switches 2 NO contacts, is not illuminated, and is rated IP65 at the front, so it works purely as an access-control element rather than an operator display.

Selection Notes
Fit this element where a position change must be restricted to key holders, such as switching a machine between Auto and Setup mode: the key is designed to withdraw only in defined positions, so an operator without the key cannot move the switch out of that state. Its 50,000-cycle rating fits infrequent, controlled use rather than continuous cycling, and the two supplied keys allow one spare to be kept separately.
