I have some device with a connection terminal which can deal with (quote)

max. 1 A/24 Vac/dc.

I would like to use it for switching a device with 1A and 12V AC. How are the specifications meant? Is the peak value (since it says max) or the RMS current/voltage meant? Since 1A AC will exceed 1A in the peaks I am afraid to break my device if I tried.
