C&K KMR7 Tactile Switches
C&K Components KMR7 Microminiature Tactile Switches for SMT come with top-actuated, watertight sealed IP67 rated, along with gullwing type terminals. The KMR7 offers an excellent tactile feel greater than 25% for an actuation force of 2N to 4N with a bounce time of ≤3ms. These tactile switches can operate in the temperature range of -40˚C to +85˚C for silver-plated and -40˚C to 125˚C for gold-plated switches. This microminiature top-actuated tactile switch features ultra-low current capabilities with a minimum current of 1mA and a maximum current of 50mA. Typical applications include consumer products, instrumentation, computer products, and industrial systems.
