A selector can be:

  • a Reggae DJ (who selects music to play).
  • a DNA probe used in the selector-technique (used in molecular diagnostics)
  • a switch used to choose which function a device will perform
  • a special kind of switch used in computers to connect multiple lines (I/O) to a single line. A related component is the multiplexor. Both components are used in the execution of conditional logic such as memory addressing and device selection and signaling.
  • a person who purchased land by "conditional purchase" under the legislation relating to crown land management, passed in 1861 in the Colony of New South Wales in Australia. The legislation allowed for ‘free selection before survey’ and was closely identified with John Robertson (Secretary for Lands).
