C&K's PTS636 series tactile switches offer a small (6.0 mm x 3.5 mm) form factor in SMT version. Their three heights and four available actuation forces are ideal for general usage applications. They include ground pin options on the 2.5 mm height version.

Previously, PTS635 and its very limited offering was C&K's only alternative on the 6.0 mm x 3.5 mm style. However, they are now enlarging the family with the PTS636 and its more options on forces and styles with a far better price level. PTS636 is the ideal solution for non-demanding consumer grade applications.

• 6.0 mm x 3.5 mm footprint: compact size for easy design
• Multiple heights (2.5 mm, 4.0 mm, and 5.0 mm): accommodates multiple integration constraints
• THT or SMT type: fully integrated into standard process
• Ground pin option on 2.5 mm height: integrated ESD protection for easy routing of unwanted overload

• IoT devices
• Home automation
• Remote controls
