About Products :

These Capacitive Switch Panels are operated by just touching them with our fingers. As the Capacitive Switch Technology used is based on a solid state circuit, the life of these switches is virtually infinite and will last the life time of the product in which they are used. Capacitive touch switches can be offered on any di-electric panel like Plastic, Glass, Wood, Granite Tiles, etc. The Capacitive touch circuit can be embedded in the di-electric material itself so that the Capacitive switches remain unaffected by harsh environments. The switches can be offered as Momentary or in Latching mode. (Toggle).

Technology :

The Capacitive Switch Technology is based on Charge Detector (CD) Technology. When any user touches the key / switch / sensor area the capacitive charge from the user’s body is detected by a the Capacitive Switch circuit, and the signal is passed on to the system. The solid state nature of the circuit makes the life of such a switch virtually infinite.


Capacitive Touch Switches are one of the most versatile switches as they can be operated by a mere touch of the finger. As the Capacitive touch circuit can be embedded in any di-electric, it makes them impervious to all external factors like temperature, dust, humidity etc. As the Capacitive Touch Switch module does not have any contacts, the switches can easily last a lifetime. This has made Capacitive switches very popular in consumer electronics (Ipod), Kitchen Appliances (Cooking Ranges), Access Controls (Door Openers), Process Controls (Elevator Buttons), etc. Enquire Now
