Key for single-pole switching mechanisms, 1 element, graphite, Simon K45. Changing the look of a room is as easy as clicking on the frame with any of the keys available in the Simon K45 series. In this range, we offer the Key for single-pole switching mechanisms, 1 element, in graphite color. For installation, the use of a universal flush-mounted box or, alternatively, a surface-mounted base is required. This key is available in half-module versions, although it does not allow combining two control mechanisms with a narrow key on a Simon 500 Cima to Simon K45 adapter plate. The key, measuring 45x22.5x10mm, has been manufactured with halogen-free thermoplastic, materials that guarantee non-flame propagation in case of fire and low toxicity in case of smoke emission, thereby increasing the safety of electrical installations.
