5 Things to Consider When Choosing a Capacitive Switch<\/h1>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

Capacitive switches<\/a> have become a popular alternative to Mechanical switches<\/a>. They are characterized by the use of sensors to measure a voltage. The voltage is constant by default. When you touch a button, though, your finger will absorb some of the voltage. The capacitive switch<\/a> will then respond by opening or closing the circuit. Below are five things to consider when choosing a capacitive switch<\/a>.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

1. FPC or PCB<\/h3>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
\n\t\t
\n\t\t\t

All Capacitive switches<\/a> feature a circuit. While some of them have a Flexible Printed Circuit (FPC), however, others have a Printed Circuit Board (PCB). When choosing a Capacitive switch<\/a>, you\u2019ll need to decide whether an FPC or PCB or right for you. FPCs are flexible and support smaller, lower-profile designs. PCBs, on the other hand, are simpler and less expensive.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

2. Overlay Material<\/h3>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
\n\t\t
\n\t\t\t

What type of material is the overlay made of? The overlay is the outermost layer. All switches have an overlay \u2014 and capacitive switches<\/a> are no exception. You can find overlays in different materials. For capacitive switches<\/a>, some of the most common overlay materials include plastic, acrylic and glass.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

3. Backlighting<\/h3>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
\n\t\t
\n\t\t\t

You can choose a capacitive switch<\/a> with or without backlighting. Backlighting is optional. You can order a capacitive switch with backlighting so that it\u2019s easier to see and use in low-light conditions. Backlighting for capacitive switches typically consists of light-emitting diodes (LEDs), which may leverage light guides for better light distribution.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

Light guides don\u2019t produce light. Rather, they are only designed to distribute light. The LEDs will produce light that travels through the light guides, at which point the light will be distributed throughout the capacitive switch\u2019s overlay.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

4. Adhesive<\/h3>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
\n\t\t
\n\t\t\t

Don\u2019t forget to consider the adhesive when choosing a capacitive switch<\/a>. Capacitive switches require adhesive to seal the overlay. Not all adhesives will work, though. Because capacitive switches<\/a> are designed to measure a voltage, the adhesive must be nonconductive. It must also be able to withstand light and moisture without degrading.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

5. Colors<\/h3>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
\n\t\t
\n\t\t\t

You can order a capacitive switch<\/a> in custom colors. Regardless of the application, you don\u2019t have to choose a capacitive switch in a generic color scheme. You can choose a custom color scheme. The colors won\u2019t affect the performance of a capacitive switch<\/a>. Nonetheless, it will improve the capacitive switch\u2019s aesthetics. Along with the type of circuit, overlay material, backlighting and adhesive, you may want to consider the colors when choosing a capacitive switch.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>
