  • Patent number: 8354603
    Abstract: A switching device includes a switching appliance, a cap, at least one connecting device for firm connection of the switching appliance to the cap, and a monitoring device. In at least one embodiment, the monitoring device includes a sensor and a tripping element, whose position is variable after connection and which, when the switching appliance is ready to operate, is located in a position in which the tripping element can be detected by the sensor, the monitoring device further including a signal unit which is connected to the sensor and is used to signal operational readiness once the sensor has detected this.
