Thumbwheel switches are rotary switches used for entering numerical data or setting limitations in electronic devices and industrial equipment. They are characterised by a rotating wheel or drum with printed digits or characters, which can be turned with a thumb or finger to choose a specific value.
Within the switch, the rotating wheel is joined to a set of electrical contacts. As the wheel rotates, different contacts are opened or closed, generating a unique binary code corresponding to the selected digit. A digital circuit can then read this code to register the input.
Thumbwheel switches can be found in a wide array of applications, such as:
Thumbwheel switches are dependable and user-friendly solutions for numerical data input and parameter setting in various electronic and industrial applications. Their modularity, clear visual readout, and robust build quality make them a popular option for many designers and engineers.
