New Low-Profile, Keypad Tact Switches from ITT Electronic Components Ideal for Handheld Applications

SANTA ANA, Calif. - November 15, 2005 - A new range of low profile, keypad tact switches is available from ITT Electronic Components. Combining high performance, usability and robustness, the KMX series offers users a pleasant, tactile feel together with a fast switching response.

At only 0.58mm thick, the KMX series employs an extremely slim switch design. Normally open, the switches close with an audible click, a robust mechanism that is certified for 250,000 cycles. The long travel distance also supports a better feeling for the user than a standard keyboard.

With area dimensions of 4.3mm x 4.1mm, the KMX series also saves PCB space compared to dome array- and keyboard-style interfaces. Each KMX series switch attaches to the board via four gull-wing terminals, providing good co-planarity and reliability. The KMX switches also use stand-off terminals, which leaves a lot of space under the switch for PCB traces.

Switches are available with or without an actuator built-in to the assembly (the KMX1 and KMX2 parts, respectively), a feature that provides a better-centered actuation. Each switch incorporates a ground pin for ESD protection. Gold and silver contact plating options are supported and the device is compliant with the Restriction of use of certain Hazardous Substances (RoHS) Directive.

The KMX series switches are suited to a multitude of applications requiring a comfortable, miniature, robust keypad with a long life. These include: PDAs, smart phones, MP3 players, cameras and key fobs. They can also be used in systems requiring a customized keyboard interface.
