摘要： A circuit is provided which, when connected in series with a service, allows that service to be powered or unpowered depending on whether the power supply is continuous or it is temporarily interrupted. That is, by switching ON or switching ON-OFF-ON the service will be powered or unpowered.
For instance in a house or hotel bathroom, the circuit can be used to select whether a fan operates when the lights are on. This can be achieved by connecting the lights directly to the single make-or-brake switch and connecting a fan in parallel through the circuit. Then switching ON or ON-OFF-ON would select whether or not the fan operates when the lights are on.
The second example relates to a bedroom or hotel room. The circuit could be used so that if the lights are switched ON, blue lights come on and some seconds later, white lights also come on. If the switch is cycled OFF-ON before the white lights come on, the blue lights come on again but the white lights remain off.
