The AZ16 Series is in a class by itself ... providing many design innovations to protect workers from injury. The Series AZ15/16 is a safety interlock switch with separate actuator key designed for use with movable machine guards/access gates which must be closed for operator safety. Their positive-opening NC contacts provide a significantly higher level of safety than conventional spring-driven switches whose contacts can weld or stick shut.

The IP67 rated thermoplastic housing makes them ideal for interlocking safety guards in hostile environments. It features a non-removable actuating head and highly tamper-resistant actuating mechanism which is difficult to defeat with simple tools, tape, bent wires or other readily available means. This rugged, tamper-resistant design ensures safe, reliable long term performance and reduces liability exposure.

The AZ16 has a wide selection of options and accessories such as LED’s, gold contacts, flexure-mounted actuating keys and universal mounting kit. These enable easy installation and effectively address a wide variety of machine guard interlocking applications – without compromising operator access/productivity. That’s why the AZ16 is one of the best selling safety switches in the world.
