The K12S Series key switches now include a version sealed to IP67 standards for use in outdoor applications such as automotive door locks, trunk openers, motorbike handles and other environments likely to encounter harsh conditions. An IP40 version of the switch is available for less demanding environments. C&K now offers the K12S Series switches in DPST, dual-contact versions with a double-step actuation of 6/12N. “The unique design of the K12S Series separates the electrical and mechanical functions of the switch,”
The entire line of K12S Series key switches feature gold-plated, self-cleaning contacts with low contact resistance (<100mΩ), 100N overload resistance and life cycles of 1.000.000. The switches’ low PCB-mounted profile makes them ideal for mechatronics design engineers to integrate into complex sub-assemblies requiring precise control for joysticks, remote controls, vehicle cabins and forklift/crane controls. In the DPST configuration, the K12S Series meets safety requirements for demanding applications in medical, military, avionics or industrial equipment.
