The tactile switch in question is a compact, surface-mount technology (SMT) component with an outline dimension of 5.2 x 5.2mm. It serves as a reliable and versatile alternative to various switches from renowned brands such as CUI Same Sky, Alps Alpine, and C&K. One of its key features is the adjustable actuator height, which can be specified as 1.5mm, 1.7mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, or 4.3mm above the printed circuit board (PCB).

This switch is designed for applications requiring precise and tactile feedback, making it suitable for user interfaces in electronic devices. Its SMT packaging ensures easy automation in manufacturing processes, reducing assembly time and cost. The switch can endure repeated activations, maintaining consistent performance over its lifespan.

Compatible replacements include CUI Same Sky switches like TS18-5-15-SL-260-SMT-TR and TS18-5-17-SL-160-SMT-TR, Alps Alpine’s SKQGA series (e.g., SKQGADE010, SKQGABE010), and C&K’s PTS526 series (such as PTS526SK15SMTR2 LFS and PTS526SM15SMTR2 LFS). Its dimensions and performance characteristics make it a suitable substitute for RS-187R05A2-DS MT RT and other similar switches, offering designers a flexible and reliable option for their projects.
