<p>Electric power switch housed in a housing (B), operated manually by a toggle or button (I) and connected to ends (V and W) of an electronic power cord supplying power to an electrical appliance or apparatus. In the housing (B) there is a built-in cyclical electronic control timer which when the commutator (S) is in the "stand-by" position continuously stores during a gliding period of time (cycle) the schedule of sequences of on/off power switchings, as commanded by the user operation of (I), into an electronic memory. When the commutator (S) is in the "simulation" position, operation of the electric power switch is taken over by the electronic control timer, which implements power switchings cyclically and indefinitely according to the schedule of sequences of on/off power switchings stored in said memory during the cycle immediately preceding the transition from the "stand-by" to the "simulation" mode of operation and as long as the commutator (S) stays in the "simulation" position.</p> |
