If the switch is installed on a QM interior (31`` wide box) built before 1961 there is no replacement available. If the switch is installed on a QM interior (31`` wide box) built after 1961 but before 1984 the replacement is a QMB362T. If the switch is installed on a QW interior (38`` wide box) built before 1984, the replacement would be a QMB362T along with a QMB306EX.
