A control system (10) is built with functional modules expandable system, usually containing electronic circuit boards (24). The packaging of the modules allow a variable number of modules to be vertically stacked together to form a variably sized control system. There is a module having a housing which engages the housing of an abutting module in a physically locked relationship, based upon four locking elements. There are modular units (16, 18, 20) which can be joined vertically by having two interlocking control units in the front of each module and two interlocking control units in the back of each module. Placed above the uppermost intermediate module is a top module (12) for the control unit. Placed below the lowermost intermediate module is a bottom module (14) for the control unit.
