C&K Components offers the AP and HP Series of sealed push-button switches, both featuring extended life cycles to 1 and 10 million actuations, respectively. Switches feature simplified assembly, are sealed to IP 67 specifications, and offer a solution for harsh environments with excessive shock, vibration, and contaminants, including off-highway and industrial applications. The HP Series switches employ a Hall-effect design with a noncontact system and also can have redundant linear hall devices. Input voltage is 5 V dc, with a programmable output voltage range from 0.5 to 4.5 V. AP Series switches have the ability to incorporate illumination and are available with a snap-in or threaded bushing. The momentary action AP Series switches feature a total travel of 2.3 mm (0.09 in). Operating temperature range for both series is from -40 to +85°C (-40 to +185°F).
