I believe we have heard of the wide range of use of silicone keys, where the product used buttons, then silicone keys can be useful, such as remote control silicone keys, equipment silicone keys, automotive silicone keys, helmet silicone keys, almost all electronic products can be used, at this time we will have a question, what makes the silicone keys become conductive? The following Cushman & Wakefield Electronics will introduce the two conductive media in silicone keys and how to identify the conductive silicone keys:.

The two conductive media in the conductive silicone keys conduct electricity by principle.

1, (conductive black particles) principle: the mutual contact between the conductive particles, the formation of conductive pathways, so that the conductive adhesive with conductivity, the stable contact between the particles in the adhesive layer is due to the conductive adhesive curing or drying caused by. Conductive adhesive in the curing or drying before, conductive particles in the adhesive is separated from the presence of each other, there is no continuous contact, and therefore in an insulated state. Conductive adhesive curing or drying, due to the volatility of the solvent and adhesive curing and cause the contraction of the adhesive volume, so that the conductive particles are stable between each other in a continuous state, thus showing the conductivity.
2, (ink conductive) conductive ink, with conductive materials (gold, silver, copper and carbon) dispersed in the linkage material made of paste ink, commonly known as paste ink. With a certain degree of conductive properties, can be used as a printed conductive point or conductive lines.

To distinguish silicone keys from conductive silicone keys.

 1, black grain conductive silicone keys to identify the method, see whether the bottom of the key has a black dot, and the dot to have a certain thickness, but also with a textured dot, if one of these two conditions, then it is black grain conductive silicone keys.
2, ink conductive silicone keys to identify the method, the same is to see whether the bottom of the key has a black dot, and the dot is particularly thin, but also with the shape of the bottom of the key and the formation of a small black block, with nails simply can not snap off the kind of ink conductive silicone keys.
