The Metal domes offer significant advantages for applications requiring back-lit switches with tactile feedback. Here are some key points about these domes:

1. Design and Structure:

  • Four Legs: Provides stability and ensures reliable actuation.
  • Central Hole: Allows direct placement of an LED, resulting in more intense and uniform backlighting.

2. Mounting Options:

  • Can be mounted on various substrates including single or double-sided printed circuit boards (PCBs), flexible circuits (flex circuits), or membrane switches.
  • Versatile in terms of application, accommodating different design and manufacturing requirements.

3. Packaging and Placement:

  • Can be packaged in cartridges for efficient handling.
  • Compatible with tools like the Dart™ dome placement pen and the SureShot™ automated dome placement machine for quick and accurate placement, enhancing production efficiency.

4. Applications:

  • Ideal for use in devices that require back-lit switches with crisp tactile feedback.
  • Suitable for a range of industries including consumer electronics, medical devices, and industrial control panels where visibility and tactile response are crucial.

 

This makes Metal domes a versatile and efficient solution for back-lit tactile switch applications, enhancing both the functionality and user experience of the end products.

Metal Dome Structure

Metal-Dome-Structure

Snap Dome of pot flakes

Snap Dome as a metal dome. Compared with traditional silicone buttons, conductive film has a better feel and longer life. It can also indirectly improve the production of various types of switches using conductive film. efficiency. The metal spring on the dome button is located on the conductive part of the PCB (mostly located above the gold finger on the circuit board). When pressed, the center point of the spring is concave and contacts the circuit on the PCB, thus forming a circuit. , the current passes through, and the entire product can work normally. This is how it works.

Metal Dome! Widely used

Applied to TV remote controls, air conditioner remote controls, various button facilities, and other equipment.
