Round Dome Switch

1. Introduction to Round Dome Switches

Round Dome Switches are the principal touch control components largely applied in membrane switches, pushbutton switches, and dome arrays. Round Dome Switches from SHANYO Precision Electronics are accurately stamped out of high-quality SUS301 stainless steel material. They have a special curved surface design that gives a crisp click when pressed while ensuring reliable conductivity at the same time. Common diameters include 3mm, 4mm, 4.5mm, 5mm, and 6mm with customizable contact force to fit different application needs (for instance, from 150g up to 600g).

2. Features of Round Dome Switches

Highly Consistent Tactile Feel

The circular structure ensures uniform force distribution and a stable feel.

High-Quality Materials

Selected SUS301 highly elastic stainless steel ensures high resilience and wear resistance. Multiple sizes available: From a small diameter of 3.0mm to a standard 6.0mm, adaptable to various button layouts.

High-life performance

Cycle lifespans reach 500,000 to over 1,000,000 cycles, meeting the needs of long-term use.

Customizable surface treatments

Optional gold plating, nickel plating, and other processes enhance conductivity and corrosion resistance.

Compatible with dome arrays

Can be used as a single unit or in adhesive-backed dome array modules.
