Snorkel for venting a dome switch

A dome switch, comprising:

• a dome placed on a support structure, the dome being at least partially invertable to provide an electrically conductive path between first and second contact pads of the support structure;
• a spacer defining a channel, the channel including a proximal opening defined therein, the proximal opening being in fluid communication with air trapped underneath the dome;
• a tube extending from an opening in the spacer to vent air from underneath the dome;
• and
• a film over the dome and the proximal opening of the spacer, wherein the film forms a hermetic seal to at least one of inhibit and prevent air from reaching the dome other than through the channel.

A method for constructing a dome switch, comprising:

• providing a dome over conductive pads of a circuit;
• aligning a first channel constructed within a first spacer with the dome, a proximal end of the first channel being in fluid communication with air underneath the dome and the first channel extending along a length of the circuit to a stiffener;
• aligning a second channel constructed within a second spacer to a distal end of the first channel, the second channel being at a different height than the first channel;
• and
• sealing the dome over the circuit to at least one of inhibit and prevent air from reaching underneath the dome other than through the first channel.
