APEM IX Harsh Environment Pushbutton Switches

APEM IX Series Pushbutton Switches are compact, waterproof pushbutton switches with a backlit switch, 12mm bushing, and a flexible elastomer membrane actuator. The flexible elastomer membrane provides no space between the actuator and the bushing, guaranteeing an IP69K panel sealing. This membrane provides excellent resistance to frost, sand, and other contaminants. The ultra-thin design offers an ergonomic advantage with tight matrix mounting. The IX switches allow multiple customization options. APEM IX Series Pushbutton Switches include 9 different actuator colors, illuminated markings with 5 different LED colors, and several different marking symbols. Illumination can also be limited to just the symbol or the entire membrane actuator.
