Capacitive Switch

Capacitive keypads and switches use individual sensors that form electric fields and act like a capacitor plate. This field penetrates a variety of materials; the most commonly used is glass. When a user touches the field, he causes a signal to be triggered. In addition to buttons, it is possible to integrate a capacitive touchpad.

Features:

• Available as illuminated or non-illuminated version
• Can be operated by light touch.
• Pushbutton works wear-free, as there are no moving parts.
• Function control by means of integrated microcontroller.
• Switching output characteristics is adjustable by firmware.
• Maximum front glass thickness is 6 mm glass or 3 mm plastic screen.
• Flat design.
• Two different output types can be provided by means of variable components between
  • default: potential-free contact.
  • on request: Open Collector
• CE-conform according to EN 50581:2013
• Cable included

Additionally for the illuminated button:

• The button-light is dimmed in standby mode
• The active mode is indicated by changing the lighting brightness
• RGB-LED lighting color is adjustable by firmware

Installation instructions:

• Remove protective paper
• Clean and degrease adhesive surface with isopropanol
• Bring the surfaces to be bonded together and bond without bubbles

Application areas:

• Equipment and apparatus engineering for all applications.
• Aerospace.
• Industry production facilities.
• Medical Areas.
• Embedded Systems.

Advantages of capacitive switches:

• Excellent resistance to water dust.
• Good haptics for the individual switches.
• Almost unlimited design possibilities.

Technology:

• Surface coating is possible.
• Implementation as a single switch, keypad, or keyboard in full layout.
• Supplementary additional features such as lighting or operating feedback as an acoustic signal or local vibration.
• Attractive additional features possible: illumination or multi-color.
• Protected by integration on the back and therefore almost wear-free
