Thumbwheel Switches

A thumbwheel switch is a type of switch that converts numbers to binary, decimal or hexadecimal code in your electronic circuit. The converted code then forms on and off signals.

How do thumbwheel switches work?

Thumbwheel switches are typically made from a case, push buttons, slider, rotor, seal plate, packing, PCB and end caps.

When installed in your electronic or digital device, thumbwheel switches allow you to input codes and numbers by manipulating the circular wheel with your thumb (hence thumbwheel). Thumbwheel switches are commonly used in instrumentation, process controls, testing and machine controls.

Types of thumbwheel switches

Thumbwheel switches differ in their mounting method. For example, some thumbwheel switches have a lock function that locks the set values and prevents them from being changed. Others can only be operated with a pen tip or other thin object. When selecting a thumbwheel switch, consider the size of the device the switch will be mounted in and choose accordingly.
