The alternate static source when switched with this type of (2 way switch) will
supplement the original static source - not replace it.
A 3-way switch which selects from either Source A or Source B seems to be a
requirement
for some aircraft (l know this may not be applicable to the LAA).
Looking at the nice diagrams in FAA AMT Vol2 Figure 10-25 shows a 3-way switch.
See attachment.
Is a 2-way switch acceptable?
