1. A modular electronic device comprising:

  • (a) housing means of an insulative material defining an internal chamber, said housing means including parallel planar first and second major surfaces, side walls and end walls;

    (b) one of said side walls having an elongated slot of predetermined width extending inwardly along the entire length of the side wall and along adjacent portions of the end walls and communicating with the internal chamber defined by said housing means;

    (c) a side wall oppositely positioned from said elongated slot including an integral projection extending therefrom with an outwardly opening recess for receiving an implement to facilitate removal of said housing means from an installed position within an electronic apparatus; and

    (d) electronic device means mounted within the internal chamber of said housing means and completely enclosed thereby, said electronic device means including electronic circuit means and a plurality of electrical contacts connected to said electronic circuit means for coupling said electronic circuit means to an external apparatus, said contacts being disposed in substantial alignment with the slot in said side wall of said housing means, said electronic circuit means and said plurality of electrical contacts being accessible from the exterior of said housing means only via the slot in said side wall, the width of said slot being sufficiently small so that the electronic circuit means and electrical contacts are not accessible to a human finger or other object of comparable or larger dimensions, thereby preventing wanton contact and tampering with the electronic circuit means and electrical contacts.
