Designed like a conventional pushbutton, the Apem FD series combines a technology of superposed filters that react to green and red light only. These switches are available now from TTI Europe.
This technology permits the display of two different legends depending on the illumination colour. With two different legends on a single switch, the series is ideal for integrated designs where extra switches or indicators are no longer necessary.
The series offers quality screen printed legends with a uniform luminosity without hot spot. Large size, snap-in and threaded bushing versions are also available with sealing up to IP69K offered. The switches are resistance to shocks and vibrations. Operating temperature is between -40C to +75C (40F to +167F). The electrical life at full load for momentary models is one million cycles (gold plated contacts), 400,000 cycles (silver contacts) and latching models offer 200,000 cycles. The mechanical life momentary models provide one million cycles and latching models 200,000 cycles.
Typical applications include transportation, telecommunication, security, medical applications, commercial vehicles, industrial automation, luxury cars, sports cars, and motorcycles.
