A '''clicker''', sometimes called a '''cricket''',<ref>{{cite web|url=https://www.dday-overlord.com/en/material/equipment/cricket|title=The D-Day Cricket|date=19 February 2016 }}</ref> is any device that makes a clicking sound, usually when deliberately activated by its user.

They usually consist of a piece of thin [[metal]] or plastic held in a casing so that the metal is slightly torqued; depressing one end of the metal causes it to pop out of alignment and releasing it causes it to pop back into alignment, each time making a sharp click.

With some clickers, the user depresses the metal directly with thumb or finger; with others, a button extends above the surface of the casing so that depressing the button makes the metal click.
