Thumbwheel Switches are a device that accomplishes its function using a rotary disk with the output code variations of BCD, decimal, hexadecimal, octal, resistor decade, or SPDT. Actuator types include leverwheel, pushwheel, rocker, or thumbwheel. Other characteristics are readout, number of sections, display characters/height, actuator type, contact rating, and mounting type.

Compare SPST and SPDT toggle switches, understand AC/DC ratings, and follow wiring examples. Check contact action, mounting and parts in the ChipApex catalog.
