The tactile switch, also known as a tact switch, is a compact and reliable electronic component with an SMT (Surface Mount Technology) design. This particular model features an outline of 3.9×2.9mm, commonly referred to as a 3x4mm tact switch, and incorporates J Hook leads (SMD tab) for easy mounting on printed circuit boards (PCBs).

The switch offers a range of actuator height options off the PCB, including 1.5mm, 2.0mm, and 2.5mm, providing versatility for different applications and user preferences. Its robust construction and precise actuation make it a suitable replacement for various high-performance switches, such as the C&K PTS820 Series and CTS Electrocomponents 226HJ1 series.

Compatible with a wide array of electronic devices, this tactile switch can serve as a direct alternative for models like PTS820J20MSMTR LFS, PTS820J25MSMTR LFS,PTS820J15MSMTR LFS,PTS820J15KPSMTR LFS,PTS820J15KSMTR LFS,PTS820J15MPSMTR LFS and others within the PTS820 Series, as well as CIT relay models such as CS1213AJF260 and CS1213BJF160. Its small footprint and reliable performance ensure that it is well-suited for applications requiring precise and tactile feedback, such as keyboards, remote controls, and other user interface devices.

Overall, this tactile switch combines compact size, ease of mounting, and versatile actuation options to provide a reliable and efficient solution for a wide range of electronic applications.
