  • Circuit for monitoring the operativeness of current-consuming electrical devices
    Patent number: 4041451
    Abstract: The monitoring circuit includes an indicator operative when activated for providing an indication. A control circuit is operative for activating the indicator when proper current ceases flowing in the current path of the monitored electrical device. The control circuit includes a reed switch connecting the indicator to the current path of the monitored electrical device and operative for controlling the activation of the indicator. An inductive component is connected in the current path of the monitored electrical device and generates a magnetic field which controls the operation of the reed switch in dependence upon the flow of current through the current path of the monitored electrical device.
