C&K has developed an ultra-miniature pushbutton switch. Designated the FP series, these RoHS compliant and compatible sealed switches are available in both vertical and right angle mount configurations, and feature an extended operating life to 50,000 cycles.

The FP series switches measure just 5.6 mm x 7 mm with a board height of only 5 mm for the right angle version and 4.5 mm x 7 mm with a board height of only 5.6 mm for the vertical version. With its ultra miniature size and versatility via the vertical and right angle mount configurations, these pushbutton switches are ideal for use in telecom and datacom applications.

The FP Series switches feature gold over nickel-plated contacts and are available with or without a white, black, or red cap. The FP series switches feature a contact resistance of 10 mA @ 2 V_DC, with an initial contact resistance of 80 mΩ maximum. Dielectric withstanding voltage is 500 V_DC between terminals (1 minute), while insulation resistance is 500 MΩ minimum @ 500 V_DC. Typical bounce time is ≤10 ms. Maximum operating force is 6.9 N and mechanical travel is 1.0 mm. Operating temperature ranges from -20°C to +80°C. The FP series switches are available in tray packaging.
