Type M2 switchboard (1915 to 1926)	Back	Up	Next
These switchboard models were based on the M2 singlephase and M2P polyphase meters. The 'S' versions had a rectangular glass case and all the internal parts were either polished or lacquered. The 'A' version was the "poor man's" version of the 'S' version with a pressed glass cover and unfinished internal parts.
