These touch panels can have graphic overlays using plastics, glass or any non-conductive material. We can add our uniform-diffuse LED back lighting, audio feedback or custom mechanical enclosures. A great example of this capability of ours is the USB Capacitive Touch QWERTY keyboard shown here.
Project Description
RapidKeypads.com, a division of Blue Sparq can design, develop and manufacture custom USB keypads with driver electronics. These custom keypads may use the standard USB HID protocol. This not only means we can emulate any button of your computer keyboard, joystick or mouse, but also means no software drivers are required.
These touch panels can have graphic overlays using plastics, glass or any non-conductive material. App store 4s. We can add our uniform-diffuse LED back lighting, audio feedback or custom mechanical enclosures.
A great example of this capability of ours is the USB Capacitive Touch QWERTY keyboard shown here. This is a PCB type keypad and has an acrylic overlay and a uniform-diffuse LED back-lighting.
Notice, there are no moving parts. This means no dirt, dust or grease is going to go between the plastic caps and the buttons. This ensures the keyboards work well for a long period of time. Because the keypad uses subsurface sensing, it is very easily cleaned and disinfected. This makes it ideally suitable for medical devices, industrial applications, CNC controllers, PLC machines etc.
We have also developed a USB subsurface mouse touch pad. This mouse can easily be combined with our capacitive touch keyboard giving you full control over a computer or kiosk. Click here to see our USB Capacitive Touch Mouse in action!

Esp32 Capacitive Touch Keyboard
Capacitive sensing is a technology based on capacitive coupling which takes input as human body capacitance. This technology is used in a capacitive keyboard also known as Touch sense keyboard or capacitive sensing keyboard. A capacitive keyboard is a type of computer keyboard that uses a change of capacitance on the capacitor pad.
The working of capacitive keyboard is similar to that of a typical touch screen smartphone. When we touch the screen, a small electrical charge is transferred from our body to this switch. This causes a change in the capacitance. The switch then detects this change and responds with an appropriate command.
Backlighting on the glass provides capacitive sensing keyboards a beautiful and aesthetically appealing appearance with strong graphic clarity. Capacitive touch control switches do not require the user to touch the metal directly as a printed glass is placed on the PCB which can eliminate potential safety hazard. As it has no mechanical components, it doesn’t wear out easily and has a long lifespan. Capsense keyboard can be used where hand-hygiene is important as these keyboards are also easy to clean using disinfectants and thus reduces the risk of cross contamination.
