This article explains the essential parameters of snap dome you need to know before inquiring, including shape, press force, diameter, and plating options.
Essential Snap Domes Parameters to Know Before Making an Inquiry
We often receive inquiries about snap domes (metal domes) from customers, but sometimes the required parameters are not well understood. To help you make an informed inquiry, here are the essential metal snap domes parameters you need to know:
1. Shape
The first parameter to consider is the shape of the snap dome. The common shapes include:
- Circle: Offers uniform tactile feedback.
- Four-Leg: Provides stability and is widely used in various applications.
- Triangular: Suitable for compact designs where space is limited.
- Oblong: Ideal for narrow spaces and specific design requirements.
Choosing the correct shape is crucial for the performance and integration of the snap dome in your product.
2. Press Force
The press force of the snap dome is another important factor. It determines the amount of force required to actuate the dome. Common press forces include:
- 280g
- 300g
- 350g
Selecting the appropriate press force ensures optimal tactile feedback and user experience. Consider the end use of your product to choose the best suitable force.
3. Diameter
The diameter of the snap dome depends on your PCB circuit board design. It’s important to select a diameter that fits well with your PCB layout. We can provide a PAD design for your PCB if needed. Ensuring proper diameter alignment enhances the reliability and functionality of the snap dome.
4. Plating
Plating options for dome snaps include:
- Nickel Plated: Offers good conductivity and resistance to corrosion.
- Silver Plated: Provides excellent conductivity and is ideal for low-resistance applications.
- Gold Plated: Ensures the highest level of conductivity and durability, suitable for high-performance applications.
Choosing the right plating option affects the longevity and performance of the snap dome in your application.
Other Considerations
- Actuation Life: The number of cycles the snap dome can endure before failure.
- Operating Environment: Conditions such as temperature, humidity, and exposure to chemicals.
Understanding these parameters helps in selecting the right snap dome for your application. If you still have questions or need further clarification, please feel free to contact our professional sales staff. We are here to provide detailed information and assist you in making the best choice.
