Gamepads with triggers
Triggers
— auxiliary controls located on the top of the gamepad on the back of the case. Triggers are pressed using the player's index or middle finger.In classic gamepads and joysticks, triggers are used to control various actions in games (for example, accelerating a car in racing, shooting in shooters, etc.). Moreover, in some models it is possible to press the trigger halfway for conditional aiming in the game or fully to fire at opponents. Also, such buttons can have a feedback function via vibration. The vast majority of triggers are based on potentiometers (variable resistors), less often on Hall sensors, which monitor changes in magnetic field fluctuations and do not have rubbing parts in their design (but are also more expensive).
Triggers are arranged somewhat differently in overhead gamepads for smartphones (see “Type”). Often, such controls are equipped with trigger-type mechanisms and moving contacts that are sensitive to the touch layer of the screen, which touch a certain area of the display when the triggers are pressed. Depending on the layout in the game, different control functions are supposed to be assigned to the triggers (shooting, aiming, squatting or jumping, etc.).
