Abstract
A circuit for detecting trouble in a sliding contact mechanism comprising a fixed contact portion and a movable contact portion, said fixed portion being connected to an electric power source. A radio-frequency signal is generated when insufficient electrical connection is caused in the sliding contact mechanism by, for example, depositing dusts thereon, said signal being delivered to a suitable alarm device to indicate the troublesome state.
