A detent is a mechanism that locks a moving part in a predetermined position. It typically consists of a spring-loaded plunger or ball that engages with a notch or recess in the moving part. Detents are used to provide tactile feedback and prevent accidental movement of a component.

The primary function of a detent is to create a point of resistance, indicating to the user that a specific position has been reached. This is common in controls such as gear selectors, rotary switches, and adjustable levers. The "click" or distinct feeling associated with a detent confirms that the component is securely in place, whether it be a specific gear, a setting, or a locked position.

Detents can vary in their design and strength. The force required to overcome a detent can be adjusted by altering the spring tension or the shape of the engaging surfaces. More robust detents are employed where greater security against unintended movement is required. Conversely, lighter detents offer a subtler indication.

Applications of detents are widespread. In automotive transmissions, they ensure the gear is firmly in place. In electronics, rotary encoders with detents allow for precise selection of settings. Many adjustable tools and equipment utilize detents to maintain specific configurations. The simplicity and reliability of detent mechanisms make them a popular choice for many mechanical and electromechanical applications.
