An electric device for monitoring the usage of equipment that is being shared by one or more entities or individuals during a predetermined schedule and that needs to be made available to any one of these entities or individuals outside that schedule. The device includes timing means programmable for any schedule and capable of activating complementary relays, one of them a normally open and the other one a normally closed. The contacts of one of these relays being connected to a suitable point in the equipment being shared so that its operation may be interrupted or turned on. A plurality of second relay means, one associated with each one of the entities, are also connected to that point in the equipment so that each entity may be able to connect the equipment. Also, there is an elapsed time meter associated with each one of those second relay means so that the time that the equipment is used, outside the predetermined schedule, by a particular entity may be measured.
