A touchscreen includes an array of touch switches on a display. It is used in many lamps and wall switches that have a metal exterior as well as on public computer terminals. Each interaction with the user across the screen might have a different meaning for the device and/or the application.Ī touch switch is a type of switch that only has to be touched by an object to operate. For example, when navigating through a smartphone or using an application, the touch sensor captures the human touches or the applied pressure across the screen. Each physical stroke that a touch sensor records is sent to a processing unit/software that processes it accordingly. Typically, touch sensors are used as a means to take input from the user. Touch sensors are used in consumer tech devices such as smartphones and tablet computers. Unlike a button or other more manual control, touch sensors are more sensitive, and are often able to respond differently to different kinds of touch, such as tapping, swiping and pinching. With your finger removing from the sensing area for 12s, the mode will be switched back to low-power consumption mode.Ī touch sensor primarily works when an object or individual gets in physical contact with it. If there is a touch around the sensing area, the module will output high level accordingly, the mode will be switched to fast mode. Generally, it outputs low level with low-power consumption mode. The capacitive inching touch switch module is based on touch monitoring IC (TTP223B).
