Abstract: Electronic digital watches may be placed in an electrically non-conductive watch case which may be molded or cast plastic, together with an electrically conductive retainer casing, and the other components usually found in such electronic digital watches including an operating and digital display module, at least one activator post and an activator switch element for each activator post. In one embodiment, the electrically conductive retainer casing retains the inner end of each activator post out of contact with its respective activator switch element, but is flexible so as to permit momentary contact of the post with the switch element when desired. In another embodiment, a tab formed in the retainer casing may be momentarily brought into contact with an activator switch element by pressure against the activator post, without the post itself being in the switch circuit.
