Metal Dome Actuators

Metal Dome Actuators

Tactile metal dome actuators are momentary switch contacts made from conductive metals that become normally-open tactile switches when utilized on a PCB or flex circuit.

To secure metal domes to the circuit layer, a custom fit pressure-sensitive adhesive tape is used. In its relaxed state (not pressed), Metal domes lie against the upper rim of their directional pathway. When pressed, the dome collapses or bends, reaching the end of its travel on the circuit layer, and, in turn closing the designated circuit. There are many various forms and actuation forces to choose from depending on your application.
