thiNcoder® Rotor

Keypad Technologies for Demanding Environments

What is thiNcoder?

The thiNcoder® rotor is an ultra-thin, non-invasive encoder that enables greater keypad design customization. Additionally, the DuraSwitch thiNcoder® rotor is the only rotary switch that can be mounted directly on a flex circuit, providing easy integration with other switches.

This patented rotary switch offers new possibilities for thin-panel design, integrating easily into a traditional flat panel keyboard. An extremely low profile delivers a thinner, lighter unit with inherent sealing capabilities against contaminants, such as dirt and moisture. These features increase design capabilities, and extends the life of your product.
