C&K KMR2 Series Microminiature SMT Tactile Switches

C&K Components KMR2 Series Microminiature Surface Mount Technology (SMT) Tactile Switches are designed to be highly responsive with an efficient tactile feel and are long-lasting to withstand harsh environments. The KMR2 tactile switches are top-actuated switches with four actuation forces. These tactile switches feature ultra-low current capabilities with a minimum current of 1mA and a maximum current of 50mA (For silver plating) and 10mA (For gold plating). Typically, KMR2 microminiature SMT top actuated switches are used in automotive, industrial electronics, and medical equipment.
