High Actuation Force | WT-Series Triangle Metal Domes

WT-SERIES

Home > Products > Standard Metal Domes > WT-SERIES

WT-Series metal domes offer a high actuation force in a relatively small dome while maintaining extensive actuation life. This dome’s triangular shape makes it ideal for applications where domes are in close proximity to other domes or components. WT-Series triangle metal domes can be mounted on single- or double-sided printed circuit boards, on flex circuits, or in membrane switch panels.
