Schneider Electric Black Key Switch, 3 Positions, Panel Mount - Harmony XB4 Series - XB4BG33 This three-position key switch from Schneider Electric is ideal for safe machine operation in industrial environments. The two contacts are separated by a central off position, so turning the switch 45° breaks all connections before you turn it to the next set of contacts. This enhances workplace safety by preventing dangerous equipment from being accidentally turned on. This switch is activated with a key that can only be removed in the off position, so it's safe to use with heavy-duty machinery. A spare key is included in case one is mislaid. • Service life of 1,000,000 cycles for reliable long-term use
