RK series is low profile microminiature SMT top actuated tact switch with different choices of actuation force and long life cycle. The switch is ideal for applications that need a high density of components in limited PCB space, such as automotive, navigation and health & medical devices. The compact top-actuated RK series comes in various product sizes (RKA2: 4.5 x 4.5 x 0.55 mm, RKB2: 4.2 x 3.2 x 2.5 mm, RKC: 3.5 x 2.6 x 1.4 mm). The RK series is available in 6 actuation forces, allowing customers easily integrate into different designs.
