Saia-Burgess Piezo Switch, Momentary, IP67, Through Hole, -40 → +105°C Green / 665629

IP68 Piezo Actuated Switches. Push ‘ switches which rely for their operation on the Piezo-electric effect. Pressure on the operating face creates a Piezo signal voltage which is internally amplified and conditioned to provide a short electrical pulse. This effects a momentary ‘contact closure ‘ of between 10 and 1000ms depending on actuation force and speed. No moving parts, High reliability and unaffected by ESD These switches are especially suitable for outdoor, low-supervision security applications. They operate over a wide temperature range and are resistant to oils and many chemicals. The switches are available in two sizes, 18mm and 25mm and in a variety of colours. Halo illumination is available in the 25mm format. Internal limiting resistors make the LEDs suitable for 24 volt operation. Connection for non-illuminated versions is by flying leads (0.22mm²) with pre-stripped and tinned ends. For illuminated Halo versions connection is made by 2.54mm pitch standard 5 way pin-header. Panel Cut Out sizes are 22.5mm for 25mm series and 16.2mm for the 18mm series
