| Why Bergquist is better: H eatSeal® Technology | ||||||||||||
| Bergquist manufactures membrane switches using HeatSeal, a proprietary dry film adhesive bonding technique developed for applications where conventional membrane switches often fail. Key benefits of HeatSeal include: Bonds top and bottom circuit layers together Protects the electrical integrity of your switches Provides permanent seal from outside environment Inadequate sealing of switch layers is a major cause of failure. Moisture, temperature extremes, and chemicals are typical enemies of standard PSA (pressure-sensitive adhesive) membrane switches. To overcome this issue, Bergquist's exclusive HeatSeal fabrication process thermally bonds switch layers | together with heat and pressure. The lamination strength is superior to pressure-sensitive adhesive construction and there is no need to externally vent the spacer layer. The result is a totally sealed switch which protects the electrical integrity of your membrane switch. Bergquist developed the HeatSeal process so you can design a membrane switch into almost any environment. Bergquist membrane switches operate under water, in dust and dirt, in high and low temperature extremes, and in critical-reliability environments such as medical where harsh cleansers are commonly used. No other membrane switch manufacturer has developed a fabrication technique as durable as the Bergquist HeatSeal membrane switch. | |||||||||||
