Since 1995  DDS elettronica has been designing and producing the electronics for vetroceramic hobs, an area in which touch control is very useful as it allows the tops to remain well sealed from fluids and dirt, as well as making cleaning easier.

The first version of touch control began with an optical switch , based on infrared technology using a transmitter and receiver incapsulated in a rubber housing. Using a microprocessor with highly complex software it was able able to detect an infra-red-emitting object on the surface of the glass (max thickness 2/3mm), while eliminating environmental 'noise' , like light , steam , and water. Today DDS elettronica have improved the system with new  'Capacitative'   technology . By using a printed circuit and special pads, the electronics are able to check an object compared to a ground level , in this case the object would be a human finger . High precision is guaranteed by measuring the signal level on the pads to a high degree of accuracy. The advantages today  are low cost in mass production , high stability and precision of measurement , no reset and adjust is necessary on first installation , and increased safety performance on water leakage  from the pot .

DDS Elettronica in this case don't have any standard product ready to sell , just the technology , however, we can customize it to suit any application on specification.

This is one of the capacitive touch control units , in production today for one of our customers .

As seen in the picture , the upper printed circuit is the keyboard with special pads (capacitive sensors), and has no protuding components, therefore no special fitting is necessary to mount the control in the cooktop .

All of the applications made by DDS Elettronica use FLASH technology , so the customer can up-date the software at anytime .

Also in the cooking sector, we have developed hardware and software applications for controlling domestic ovens . Temperature can be maintained to within 1 or 2 degrees in all cooking modes.

We have worked in this sector for many years , and because of our production line, we can produce a high quantity of electrical circuits at a competitive price , and a high level of quality .
