Patented switch solution

Combination of two technologies (optical and capacitive) for a safe release

Easy to use, elegant glass surface, flush front panel - these are characteristics that you can expect from a PCAP design. Unfortunately, there are situations where unintentional or unwanted activations of the PCAP touch screen occur, whether by electromagnetic interference or water wetting the front.

Security through redundancy

In critical applications, you want to be sure that no false activations occur. The Safety Key offers all the advantages of the PCAP sensor and combines it with an independent second level that monitors touch input with an optical measuring principle. Only the combination of two events leads to an operation being passed on to the system behind it.

Patent pending

The patent-pending process enables the development of high-quality surfaces with touch input and offers the security of a mechanical button. The Safety Key is not a finished product, but a demonstrator for the technology that can be integrated into your own products.

The demonstration device displays the status of each channel with an LED for evaluation. In the target application, only the combined output is required, which triggers the desired switch event in the subsequent device. Since touch sensors work without haptic feedback, but this is desirable for ergonomic reasons, this output can also activate a vibration motor that gives the operating finger the feedback that the desired function has been triggered.
