The TS-1087S-02026 is a tactile switch manufactured by XUNPU. It is an SMD (Surface Mount Device) part that measures 5.2x5.2x2.0mm, and is RoHS compliant. This switch is typically used as a push button and is suitable for mounting on small circuit boards. It has a metallic dome enclosed in a plastic container for protection against dust and other environmental damage, and can be used to detect input from a user when activated. Once actuated, it provides good tactile feedback and low contact resistance. This switch is ideal for applications where a small form factor is needed and is ideal for PCBs and other places with limited space. It is suitable for a wide range of applications, such as consumer electronics, automotive, and industrial applications.
