Thumb Switches - Pushwheels

A thumbwheel switch is a setting switch that converts the numeric value selected by turning a disk-shaped part on which numbers are written into a binary, decimal, hexadecimal or other code using the combination of ON and OFF signals for multiple contact circuits. This outputs the resulting code. Thumb wheel selector switches are normally configured to provide a base two output for use with microprocessor-based systems. A value is entered and a binary output that corresponds with that value is generated. The switches are single digit and several units can be arrayed together.
