If you\u2019re looking to buy a switch \u2014 whether it\u2019s for a human machine interface (HMI), industrial equipment controls, a remote controller, etc. \u2014 you should consider choosing a capacitive switch. Using the same capacitive technology as touchscreen tablets and smartphones, it\u2019s a unique alternative to traditional dome switches. With dome switches, physical contact between the key and an underlying circuit trace is needed to register a keypress. Capacitive switches differ in the sense that they identify keypresses via the user\u2019s touch. So, why should you choose a capacitive switch?<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

#1) Highly Responsive<\/h3>\n

Capacitive switches are highly responsive, meaning they \u201crespond\u201d to the user\u2019s touch as soon he or she makes contact with the key. Even a light touch will immediately trigger a keypress, making them an excellent choice for companies in need of responsive switches.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

#2) No Risk of Mechanical Failure<\/h3>\n

There\u2019s no risk of mechanical failure with capacitive switches. This is because capacitive switches identify keypresses by measuring a change in capacitance. Therefore, there are no mechanical components needed in their operation. As long as the capacitive switch is able to measure change in capacitance, it will continue to work as intended.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

#3) Low Profile<\/h3>\n

It\u2019s also worth mentioning that capacitive switches feature a low profile. Although they are customizable, they are typically designed with a sleek, slim profile to achieve a higher level of aesthetics and functionality. Low-profile switches are more attractive than large, bulky switches. Most importantly, though, they are more ergonomic. The low profile allows workers to easily and comfortably use the capacitive switch while causing little on no strain on their hands. Considering that muscuskeletal disorders (MSDs) cost employers millions of dollars each year, this is a huge benefit of capacitive switches that shouldn\u2019t be ignored.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

#4) Printed Circuit Board Options<\/h3>\n

You\u2019ll find that capacitive switches are available in both printed circuit board or flexible printed circuit board options. The former is the traditional option that features a hard board on which a circuit is printed, whereas the latter features a flexible material on which a circuit is printed.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

#5) Backlighting Options<\/h3>\n

In addition to printed circuit boards and flexible printed circuit boards, capacitive switches are also available in a variety of backlighting options. You can choose traditional electroluminescent (EL) backlighting, for example, or you can opt for the more energy-efficient light-emitting diode (LED). There\u2019s also fiber optics backlighting, which uses strands of optical fiber through which light flows to produce illumination for the capacitive switch.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>
