OTTO HTWM Rocker Switch Style Mounting

Hall Effect Mini Proportional Output Thumbwheel.

The OTTO HTWM offers the same performance as the standard OTTO HTW Proportional Thumbwheel but with a much shorter behind panel depth, ideal for use in grip, armrest and panel applications. Available with eight output options, the HTWM offers a spring-return-to-center, single axis thumbwheel actuator that provides linear change in voltage output in either direction from center. Options include increasing or decreasing voltage output from the center position to the full travel position, and single or dual (redundant) outputs per axis. The HTWM offers snap-in style mounting and a three million cycle rotational life. The HTWM electronics are sealed to IP68S and have excellent EMI/RFI immunity.

The HTWM Miniature Proportional Output Thumbwheel works well in numerous commercial applications.
