|Instructions and Precautions for Handling of Metal Domes|
|Contact Tester: Test points: 1-128 (can be extend to 256 );|
Test time: <0.5 seconds
Transition Ring: The transition ring is the visible ring on the top of the dome, where the dome radius transitions into the feet of the dome. The transition ring is the hinge point of the dome that forces the dome back to its original shape after the dome has been depressed or snapped over.
Bi-Stable: The condition of a dome where, when actuated and then released, the dome does not return to its original condition. In this state, the dome exhibits two (2) stable conditions.
Any damage to the transition ring will affect the domes ability to return to its original form, thus reducing the domes actuation force, tactile ratio, or to the extreme, cause the dome to become bi-stable.
|Damage can occur to the dome by any of the following means:|
|These are the most common causes of damage to the metal domes during assembly; yet do not include all sources caused by general rough handling.|
