I would send you one of mine "at cost" but USPS shipping alone would be ~$4 which is more than the relay module! Anyway, be sure to get one with the RELAY MODULE on it. The 4-button module shown immediately above does not use a relay (it uses transistors) and hence can only switch DC loads. Look for one with the blue (typically) cube relay. You need the relay version which can switch AC (or DC) loads.
