Sealed pushbutton switches
18 August 2010, Switches, Relays & Keypads
C&K Components has developed the FP series of miniature pushbutton switches. The RoHS-compliant and -compatible sealed parts are available in both vertical and right angle mount configurations, and feature an extended operating life to 50 000 cycles. They measure 5,6 x 7 mm, with a board height of 5 mm for the right angle version and 4,5 x 7 mm, with a board height of 5,6 mm for the vertical version.
The FP series switches feature gold over nickel-plated contacts and are available with or without a white, black or red cap. They exhibit a contact resistance of 10 m at 2 V d.c., with an initial contact resistance of 80 m maximum. Dielectric withstanding voltage is 500 V d.c. between terminals/1 minute, while insulation resistance is 500 M minimum at 500 V d.c. Typical bounce time is less than 10 ms, while maximum operating force is 6,9 N and mechanical travel is 1,0 mm. Operating temperature ranges from -20°C to +80°C. |
