The 2AK2-02 is a 22mm non-illuminated metal selector switch operator designed for industrial control applications. It features a maintained contact operation with left-side key removal capability, allowing the key to be extracted only from the left position. The operator is constructed with heavy-duty contact blocks equipped with self-wiping contacts available in silver or gold-plated options, and supports up to six circuits through stackable contact blocks (2 blocks across by 3 blocks deep). The device is certified to IEC 60947-5-1, VDE0660, CSA C22.2 No. 14-95, and UL508 standards, with an IP 65 degree of protection and NEMA Type 4X, 12 rating. Contact blocks are rated for 600V AC/DC with 10A AC or 2.5A DC capacity, featuring self-wiping slow break operation and a mechanical life of 1 million operations. This selector switch is ideal for machinery control, emergency stop systems, and process automation where reliable, durable switching with restricted key access is required.
