Evening guys,
I took my clocks out to change the outside temperature gauge, but while the clocks were out, I noticed these things and wondered what they were. Picture 1 is 3 slider switches, all selected to off. Picture 2 is what looks like a removable card. Can anyone shed any light on them?

Can't believe I've had my clocks out more times than I can count on two hands and never noticed these
