Touch Switches and Tactile Switches

 
Touch switches may come in numerous types, their primary forms being capacitance, resistance touch, and piezo touch switches. Capacitance switches operate on a single electrode, and body capacitance is used for functionality. As such, the switch is designed to charge and discharge its metal exterior until a capacitance change is detected, such as when a person touches it. Such sensor types are common to integrated circuits and short-range proximity sensor devices.
 
Resistance touch switches require two electrodes to have physical contact with a conductive object for operation, their resistance between metal pieces dropping when the conductive object is present. Simple in operation, touch switches will generally activate when a person touches the button, the device turning off once fingers are removed from the switch. Piezo touch switches, meanwhile, consist of a piezo ceramic that mechanically bends when touched, allowing it to act as a sort of actuator.
 
Tactile switches are fairly similar to touch switches, and they are known for the tactile feedback that is provided to a user when the button or switch is depressed onto a control panel or printed circuit board (PCB). Tactile switches are common to various applications, often being a common switch type on a keyboard, keypad, instrument, or interface control-panel. When procuring such components, they most often come in the form of either tact switches or keyswitches.
 
Tact switches are tactile electromechanical components that are often found on keyboards, keypads, and various interfaces. Keyswitches can also be found on keyboards and keypads as well. Dome switches are also considered a type of tactile switch, such components being placed under a rubber bubble or dome. When such switches are pressed, the dome will collapse, causing the switch to establish contact. Such switches are commonly used for consumer keyboards that are found in office settings, typically being quieter than other tactile switch types.
 
With the use of switch components, control over various systems can be established with ease. As mechanical assemblies, switches can begin to degrade over time, eventually requiring replacement for continued functionality.
