With the development of technology, all products must keep pace with the times, which is a development of the times, but also a brutal era, jungle survival of the fittest interpretation of the head. When the product technology becomes more mature, slip rings have also emerged.

       Electrical contact with the conductive slip ring is slidably connected application areas, it is also known as the collector ring, or rotary joints, rotary electrical interface, slip ring, slip ring, ring back, coils, commutator, adapters, high current slide ring is a realization of the two relative rotation body images, data, and power transmission precision signal transmission devices.

       Mercury Slip ring first originated in Taiwan, the use of mercury and a fluid conductive characteristics, researchers found that mercury conductive resistance is very small, and when the micro-slip ring is rotated little resistance, the use of mercury as a transmission medium is a very suitable slip ring material. So, people put mercury sealed up, the use of sophisticated technology, the toxic mercury sealed in a cylindrical space inside, so good to circumvent the toxicity of mercury, the advantages of the use of mercury. Mercury slip ring only downside is the price is expensive, because the mercury itself is expensive, plus sealing technology is very high, so the cost and the cost is very expensive, usually mainly used in high-end equipment and precision instruments above, the amount is not too large.

       Machinery industry continued to promote the development of innovative slip ring, in terms of quality, service life, cost-effective requirements are constantly on the increase, so Bildt electronics company came into being, from the beginning to the simple application of the revolving door cranes, tanks, etc. large machinery on the application, from a few hundred to several thousand dollars on a million slip ring slip ring ranging from every minute 50000RPM to 10,000 RPM rotational speed per minute, from simple to complex conductive exterior design procedures Bildt in constant forward, so that the customer how requirements, how do we even make technical improvements for the actual situation!

       Separate development history slip ring can be seen more and more mature technology products, technology updates faster and faster, the product's effectiveness and practicality of products is also growing stronger! Particularly suitable for unrestricted continuous rotation while rotating from a stationary position to the transmitting power or data of the place.
