As a manufacturer of precision stamped metal parts, we also specialise in the manufacture of metal snap dome contacts for use with electric circuitboards, most commonly used today in mobile telephone handsets. With over 17 years experience in this field we have built a large catalogue of over 200 readily available domes which require no need for any tooling, and are available at very short notice.

Our domes are currently being used all over the world, in many applications ranging from mobile phones, personal electronic apparatus to disposable cameras.
