ABSTRACT:
The present invention is a module frame for use in a modular electronic assembly which includes a light emitting read out source and which also includes a substrate on which an integrated circuit chip is mounted and which is electrically coupled to a pair of batteries. The module frame is non-conductive and has a substrate cavity, a conducting member cavity which is disposed adjacent to the substrate cavity, and a first battery cavity and a second battery cavity both of which are disposed adjacent to the conducting member cavity. A first battery connector is disposed in the first battery cavity and is used for coupling the negative terminal of the battery in the first battery cavity to the casing of the battery in the second battery cavity. A second battery connector is disposed in the second battery cavity and is used for coupling the negative terminal of the battery in the second battery cavity to the substrate. A conducting member formed from a conductive material and adapted to be fitted in the conducting member cavity of the module frame is electrically coupled to the casing of the battery in the first battery cavity. A pair of pushbutton switches are mechanically coupled to the conducting member so that when they are pushed they cause the conducting member to contact a conducting plate which is electrically coupled to the substrate.
