Like capacitive touchscreen devices, it uses the human body’s capacitance to identify commands. 6 Reasons to “Switch” In most cases, touchscreen switches are used to replace membrane switches, which rely on a pushbutton in order to operate. Prime members enjoy FREE Delivery and exclusive access to music, movies, TV shows, original audio series, and Kindle books. HTTM 2.7V-6V HTDS-SCR Capacitive Anti-interference Touch Switch Button Module K9. Capacitance switches are available commercially as integrated circuits from a number of manufacturers. Normally, the overlay layer is made of a durable material like plastic or glass. When backlighting a capacitive touch display, light is placed between the sensor and the cover layer of the screen interrupting the capacitive field. Of course, capacitive is only one type of touch switch. If the intrusion of dirt, dust or moisture is a concern, capacitive is probably the best option for an electrical switch. Touch switches are used in the following applications: white goods, security devices, commercial appliances, kiosks, electrical housewares and medical equipment. Considering a parallel-plate model, the electrode forms one plate of a capacitor, with the other plate being either ground or the user’s finger. Within the last decade or so, it has become difficult indeed to imagine a world without touch-sensitive electronics. 311 Winton Street The key thing to remember about capacitive switches is that they require direct contact with a conductive object to operate. As you can see, capacitive switches offer several key benefits, including versatility and longevity. Mouser offers inventory, pricing, & datasheets for Capacitive Touch Sensors.
