Overview:

		Simple structure and, thus, highly cost-competitive, durable, low-profile Available in both 4-way and center-click types Highly user-friendly operation No need to be connected with mother boards (easy to design in, 5 port support ?)

Semi-custom made type:

		Ideal for short lead-time, small production lot projects Key illumination type available as an option Standard microprocessor available. Through a connector, can be connected to your mother board easily Standard output available (USB, I2C and so forth)

Custom made type:

Low-profile. Ideal for small portable devices In addition to 360 deg analog pointing, scroll, pressure sensing operation available though the disc surface Key illumination type available as an option Made by silicone rubber. Highly cost-completive and durable

How does it work?

The rubber sensor potion to have more than 4 conductive rubbers The conductive areas will be touched to PCB Area of connection changes per the pressure and, thus, the resistance changes per the applied pressure The voltage change will be converted to the location information through a firmware.

Application Example:

PDA		Cellular Phone

Demonstration (video clip):

		Require following applications:   Windows: Windows Media Player   Macintosh: Quick Time
