A meter module assembly having at least one junction box for distributing input/output signals and electric power to on-vehicle electrical components, at least one switch unit having a plurality of switches for controlling said electrical components, and an instrument board, comprising:

• a circuit board by means of which said junction box and said switch unit are electrically connected to form a control board, said junction box and said switch unit being horizontally juxtaposed in a direction perpendicular to a longitudinal axis of a vehicle with which said meter module assembly is use;
• and
• a panel-mounting case having a first case and a second case, said first case having said instrument board mounted upright thereon in vertical and crosswise arrangement relative to said longitudinal axis of the vehicle, said first case and second case being vertically assembled together in integral construction with said control board sandwiched between said first and second cases, said first case being provided with a hole through which said instrument board is electrically connected with said control board when said instrument board and said first and second cases are assembled together.
