1. A timing device for blocking an electromagnetic signal comprising:

  • a housing having a body and a planar back wall;

    an input terminal for connecting to means external to said housing for carrying an incoming electromagnetic signal;

    an output terminal for connecting to means external to said housing for carrying an outgoing electromagnetic signal to a remote audiovisual device;

    a switch disposed within said housing and operably connected between said input terminal and said output terminal, said switch having an on position forming a closed circuit between said input terminal and said output terminal and having an off position causing an open circuit between said input terminal and said output terminal;

    a clock disposed within said housing for counting time;

    set means for manually setting said clock to a current time and for manually setting at least a first reference time and a second reference time, said set means controlling said switch to change to the on position at said first reference time and to the off position at said second reference time and thereby maintain said closed circuit therebetween;

    a cover pivotally attached to said housing for enclosing said set means, said input terminal and said output terminal;

    locking means for locking said cover to said housing;

    a power plug adapted to engage a standard electrical receptacle, said power plug operably connected to said clock and attached to said back wall of said housing, said back wall further defining an aperture for passage of a screw for threadably engaging a mating aperture of the standard electrical receptacle; and
