The movement of air is called \u201cventing<\/strong>\u201d and is important for dome sheet<\/strong> functions work properly. If Lack of venting can cause adverse affects on the feel and function of the switch. While venting is not absolutely necessary for every application, it is desirable in almost all applications. When the metal dome<\/a> is depressed, air is trapped underneath it. To avoid compressing the air under the metal dome when actuated, it is recommended that a vent channel be present for dome sheet<\/a>.
\nThe venting of the dome sheet <\/a>can be achieved a number of different ways. Some Examples: a.) vent channel can go from dome to dome via a spacer layer b.) dome arrays<\/a> can be top vented through the polyester material c.) vent channel can go through the pcb board<\/a>.<\/p>\n

At last, not properly venting of the dome sheet<\/a>\u00a0will result in significant loss of tactile response. If you need further information,please contact us<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
