May 12, 2009 — C&K Components developed two series of pushbutton switches. Designated the AP Series and HP Series, both sealed switches feature extended life cycles to 1 million and 10 million actuations, respectively.Not only do these switches feature life cycles in the millions, but they are also sealed to IP67 specifications, providing an extremely rugged solution for harsh environments where shock, vibration and environmental contaminants are a concern.
Both switches are designed for simplified assembly.The AP and HP Series pushbutton switches are ideal for use in the harsh environments of industrial applications.The HP Series switches employ a Hall effect design with a non-contact hall effect contact system, and a high-energy magnet provides a linear magnetic field for the hall device. The HP Series also has the ability to have redundant, linear hall devices.
Input voltage is 5VDC, with a programmable output voltage range from 0.5V to 4.5V and one or two available outputs. Actuator travel is 0.150” and operating temperature ranges from -40ºC to +85ºC.
The AP Series switches have the ability to incorporate illumination and are available with a snap-in or threaded bushing. The switches also allow users to order the base switch with or without the cap, providing the ability to order one base switch and multiple color caps and snap on caps during the installation process to suit each specific application. The SPST-NO, momentary action AP Series switches feature a total travel of 2.3mm. Actuation force is 2N and 4N, with a logic level current through 2A.
Operating temperature ranges from -40ºC to +85ºC.
Typical pricing for the AP Series devices ranges from $2.50 to $3.75 in quantities of 10,000, while pricing for the HP Series pushbutton switches ranges from $21.00 to $27.00 in low volumes.
Lead time for both versions is from 4 to 6 weeks.
