\"Tactile<\/figure><\/div>\n\n\n\n

Tactile Keypads are those specially created to provide an indication or feedback <\/strong>to users following the actuation or ‘key press<\/strong>‘.\u00a0For instance, when a button or key is pressed on a non-tactile keyboard, the user’s fingers press against the visual representation of the button.\u00a0The users are unaware of the exact moment they activated the button unless there is some visual indication which assures user of receipt of input being recorded.\u00a0In contrast, a tactile keypad can provide the sensation <\/em>of a snap or click that provides users with haptic feedback.\u00a0This feedback allows the user be aware that they have activated the keypad, technically by closing the circuit!<\/p>\n\n\n\n

Functioning of a Tactile Keypad<\/h2>\n\n\n\n

Linepro<\/a> manufactures a variety of standard models of keypads, which provide tactile feedback.<\/p>\n\n\n\n

Membrane Keypad or Switch<\/a> that is equipped with Polydome<\/strong> or polyester domes are fabricated into the circuit’s upper layer or the graphic layer.\u00a0There is no additional material required and the domes do not require to be installed on each of the keys.\u00a0They are generally used for bulk orders to bring down the expenses.<\/p>\n\n\n\n

Membrane Keypad or switch with Metal Dome:<\/strong> Domes made of stainless steel are typically employed in small and medium-sized keypad projects.\u00a0They have the longest life of actuation and provide a more tactile experience than polydomes.<\/p>\n\n\n\n

Silicone Rubber Keypads with Carbon Contacts:<\/strong> The silicone keypad<\/a> is mounted over a flexible circuit or a PCB.\u00a0At the lower part of the silicone, there are plungers that have carbon pills which conduct electric charge.\u00a0The tactile feedback occurs when the webbing that surrounds the key breaks down, resulting in the sensation of a snap.\u00a0The carbon is then able to touch the lower circuit, and the key is then actuated.\u00a0The key then retrieves to its initial position once fingers are taken back and ready to be used again.<\/p>\n\n\n\n

Silicone Keypad with a Metal Dome:<\/strong> In the above design, Carbon is taken out of the silicon, and the metal dome is inserted between the plunger of silicone and the rigid or flexible circuit beneath.\u00a0The dome is able to provide the sensation of a tactile touch and may make an audible click<\/strong> when the device is activated.<\/p>\n\n\n\n

Linepro has a large collection of domes that vary in shape, size and the force at which they are actuated.<\/p>\n\n\n\n

What are the advantages of using tactile keypads?<\/h2>\n\n\n\n

When a keypad isn’t tactile<\/strong> users only know that the button was activated when the device is performing some function.\u00a0This can cause confusion<\/em> over whether the button was pushed enough or in the correct manner and could lead to errors, like repeated activation.\u00a0A tactile keypad can avoid this problem by making the button snap back when it was activated.\u00a0The force of the snap is felt on the fingers, and, in certain cases, can generate a sound like clicking to further confirm that the button was actually actuated.\u00a0In addition to avoiding confusion, the keypads are also used due to other reasons, including an easy user experience (UX)<\/a>.\u00a0UX is crucial for consumer products, ensuring that customers have fun using your product.\u00a0It can assist the customer in understanding the product in a better way.<\/p>\n\n\n\n

What are the products that make use of tactile feedback technology?<\/h3>\n\n\n\n

Nearly every keypad is able to incorporate this technology; we all have probably used hundreds of them in our lifetime. This technology is frequently used in consumer and industrial applications. Some examples are below in photos.<\/strong><\/p>\n\n\n\n
