Key Selector Switches

Altech Corp.® offers high-quality key selector switches built with simplicity and reliability in every detail. Altech switches are one of the most robust 22mm heavy-duty metal operators available on the market.   Altech’s industry-standard switches are delivered in a variety of different combinations: two pole or three pole, momentary or maintained. They are keyed alike or can be keyed different, and to enhance security, several types of key removal options are available.  The switches are watertight and have been tested to meet NEMA Type 4X, 12 and IP65.

Altech’s switches are also UL508 and CSA recognized. As another benefit these switches are a direct replacement for ZB2 type key switches. Heavy-duty metal housing is the standard and easily mountable in a 22mm mounting hole. Installation of these switches is extremely simple; the only tool needed is a screwdriver. The metal mounting bracket is vibration proof and up to six different contact configurations are available. All contact blocks are made with silver contacts for industrial applications, while gold plating is available for signal switching. Silver and gold contacts can be mixed in the same switch configuration. They are rated for up to 10A thermal current and have a mechanical life of more than 1 million operations.
