C&K COMPONENTS PTS820J20KPSMTRLFS Microminiature SMT Pushbutton

The C&K PTS820 series microminiature SMT pushbutton switches are designed for space-constrained applications requiring a reliable momentary action. These switches feature a compact footprint of 3.9 x 2.9 mm and are available in three different heights (1.5mm, 2.0mm, and 2.5mm). They offer a high number of cycles and are suitable for control panels, nomad devices, remote controls, and keyless entry systems. The switches are RoHS compliant and packaged in reels for automated assembly processes. The easy build-a-switch concept allows for customization to meet specific application requirements.
