Thumbwheel switch
By Chad Elmore28 February 2019

Otto, a Carpentersville, Ill.-based manufacturer of control switches, joysticks and grips, has introduced the new HTWS subminiature Hall effect proportional output thumbwheel switch.
Smaller than the company’s HTW and HTWM series, the HTWS is a spring return-to-center, single axis thumbwheel that provides a linear change in voltage output corresponding to actuator movement in either direction from center.
It is available with eight output options, including increasing and decreasing voltage output from the center position to the full travel position and single or dual (redundant) outputs.
The HTWS snaps into a 0.895 x 0.420 in. panel opening. Electronics are sealed to IP68S, and an optional sealing boot is offered for added protection against dust, sand and water ingress.
The company said HTWS offers a 3 million cycle rotational life and EMI/RFI immunity. It is available with flying wire leads or pin connection.
