Introduction

When the application scenario is more complex than what a "standalone" switch can provide, consider using the MICRO SWITCH™ AC Series door switches. AC Series switch assemblies monitor whether a service door or panel is "closed" or "open." This series is a compact switch assembly suitable for a variety of equipment applications, including vending machine service doors or panels, truck trailer monitoring doors, and more. When a device electrically interlocked through an AC Series switch (such as a door or panel) is opened, the AC Series switch cuts power. In addition, AC Series switches can provide electrical signals to signal circuits (such as indicator lights or horns) to indicate that a door or panel is in the open position. Most AC Series switch assemblies also feature a "pull-override" position, which allows a service door to be opened while power is maintained through the switch assembly — a feature that can be useful during equipment troubleshooting. AC Series switch assemblies can be configured with up to four switch elements, providing discrete outputs to meet the needs of control and/or indication circuits. Select catalog products carry UL and CSA certifications.
