Domes Manufacturers Singapore

The metal dome achieves comparatively greater tactile with significantly shorter actuation than Poly dome, and are used extensively in telecommunication products due to the properties like Slim design & light weight, Short actuation with excellent tactile, High operating temperatures of 85°C, Excellent Mechanical Life, etc..http://www.polytech.com.sg/Domes.html

  1. Domes, Switches and Keyboards Manufacturer

  2. The keyboards of Dome-switches are generally a hybrid of flat-panel membrane and mechanical keyboards. They bring two circuit board traces together under a rubber or silicone keypad using either metal dome switches or polyurethane formed domes. The metal domes switches are formed pieces of stainless steel that, when compressed, give the user a crisp, positive tactile feedback.

  3. These metal types of dome switches are very common, are usually reliable to over 5 million cycles, and can be plated in nickel, silver or gold. The rubber dome switches are most commonly referred to as polydomes and they are formed polyurethane domes where the bubble inside is coated with graphite.

  4. While polydomes are typically cheaper than metal domes, they lack the crisp snap of the metal domes, and usually have a lower life specification. The Polydomes are generally considered as very silent material but purists has find them as mushy because the collapsing dome will not provide much positive response as metal domes.

  5. For either metal or polydomes, when a key is pressed, it collapses the dome, which connects the two circuit traces and completes the connection to enter the character. The patterns present on the PC board are often gold-plated, but both are commonly used switch technologies in mass market keyboards today.

  6. This type of switch technology happens to be most commonly used in handheld controllers, mobile phones, automotive, consumer electronics and medical devices. Dome-switch keyboards are also called as direct-switch keyboards where a special case of the dome-switch in the computer keyboard is the scissor-switch.

  7. The keys are attached to the keyboard via two plastic pieces that interlock in a scissor like fashion, and snap to the keyboard and the key. The plastic scissor connects the keycap to a plunger by using a special mechanism in the process of depressing the rubber dome with a much shorter travel than the typical rubber dome keyboard.

  8. Typically scissor-switch keyboards also employ 3-layer membranes as the electrical component of the switch. Also they have a shorter travel distance of 2 mm instead of 3.5 – 4 mm for standard dome-switch key switches. These keyboards are generally quiet and the keys require little force to press.

  9. Scissor-switch keyboards are typically slightly more expensive. Polytech has world-class practices and serves with the collection of technology and skills in the manufacturing process which includes Silicon rubber, Elastomeric, Metal/Poly dome, Plastic molding, Spray Painting, Lens and Electronics.

  10. Together collaborating with their associate companies to further enhance their most effective and efficient solution in the entire manufacturing process, they challenge themselves to give their customer's the best in Cost, Quality and Customers Satisfaction.
