Backside of the glass is also metallic coated which prevents discoloration. The switch changes output level with the presence of a finger or hand (gloved or ungloved) which makes it ideal for use as a simple on/off switch. Because of this change, the switch can identify when and where the touch occurred, which is essentially how capacitive switches work. In electrical engineering, capacitive sensing is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric different from air.

A capacitive switch is a type of touch-controlled electrical switch that operates by measuring change in capacitance. Electronic circuits with touch sensing is more Interactive to the user than traditional electronic circuits. The key thing to remember about capacitive switches is that they require direct contact with a conductive object to operate. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity, pressure, position and displacement, force, humidity, fluid level, and acceleration. Capacitive Switches Activated by change in capacitance. This is why using a stylus typically won’t work (unless it’s a capacitive stylus). It provides a smooth, sleek appearance without raised surfaces or button openings allowing for ease of cleaning and sealed designs. Resistive and piezo are two other common types of touch switches, the former of which works by lowering the resistance of two conductive components, while the latter uses the mechanical bending properties of piezo ceramic. Capacitive touch buttons have an ergonomic design that does not require force for actuation, but only contact with the surface of the button. $7.59. As you can see, capacitive switches offer several key benefits, including versatility and longevity. Touch switches are used in the following applications: white goods, security devices, commercial appliances, kiosks, electrical housewares and medical equipment. Computer input devices are indifferent to human contact as there is no reaction from software in the event of making, maintaining or breaking physical contact like touches or releases.Thus, touch sensing input devices offers numerous possibilities for novel interaction techniques.
