New IP67 harsh environment switches offer extended actuation lifecycle

29-01-2019 | TTI Europe | Connectors, Switches & EMECH

Now available from TTI Europe, the new IP67-sealed model in the C & K K12S Series of switches is ideal for outdoor applications such as automotive door locks, boot openers, motorcycle handles and similar harsh environment uses including agricultural machinery and vehicles, and off-road transportation.

The series provides a unique design that segregates the electrical and mechanical functions of the switch for longevity and robustness and is offered in SPST versions and DPDT versions. The latter meet all safety standards for demanding applications in medical, defence, avionics and industrial equipment.

The series features gold-plated, self-cleaning contacts with low contact resistance (<100mOhm), 100N overload resistance. They have double-step actuation and are remarkably robust, with a life cycle of one million actuations. These switches are low-profile when mounted on the PCB, easing integration into the design of complex sub-assemblies requiring precise control, for example, remote controls, joysticks, vehicle cabins and forklift truck and crane controls. Further characteristics of the series include compatibility with the SMT lead-free soldering process.

The switches are illuminated, with a total travel of 1.5mm and a selection of operating forces - 3N; 3,5N; 5N; 6N; 9N 4/8 N; 6/12 N. A IP40 version is also offered.
