I am using Omron 6mmx6mm tact switches. They have a square actuator that is 4mmx4mm.

They have only one height of cap for this series B32-xxxx

e.g. http://ca.mouser.com/ProductDetail/Omron-Electronics/B32-1000/?qs=sGAEpiMZZMs8I5ltipPMADjtIU7n%2f6wG

unfortunately these are too short by about 2mm to sit on the same PCB that also has jacks (all 3.5mm jacks are tall).

Are there any other brands of switch caps that might be compatible and are taller?

I made a mistake with height calculations and now I am kind of committed to having to use these omron buttons (pcbs already made :S).

i.e. rs-components / alliedelec carry 9 caps for the B32 series. according to this datasheet the square caps are all 5,5mm in height, no matter what diameter. this would result in a total height of 10mm together with the switch.

however, there is a round one, 9.5mm in diameter (B32-16x0) which would result in a total height of 11.5mm.

Hey Mattias, those caps are only for the 12mmx12mm swicthes and will not fit on the 6x6. I found instead an e-switch brand tact switch with the same footprint as the omron but it has a super tall (13mm) round actuator built in. I am just going to use this instead!
