Capacitive Membrane Keypad Capacitive switch with LCD window
Capacitive Membrane Keypad consists of one or more capacitive
buttons. The capacitive touch buttons/sensors can be printed on a
polyester film using conductive ink, or can be copper pads on a
PCB. These sensors are connected to the IC. When a button is
pressed, the IC measures the increase in capacitance and triggers a
response.
The main advantage of capacitive touch keypads are that there are
no mechanical moving parts, which will eventually wear out. These
capacitive sensors are placed underneath any non-conductive overlay
material such as AR-1 Acrylic, thick polyester and hardcoated
polycarbonate, and ABS Plastic, making them virtually
indestructible. This construction is also very easy to clean, which
makes it a good choice for medical applications.
