An electronic switching device includes a housing with at least one housing door, a lockable rotary handle rotatable at least between an ON position and an OFF position, a handle locking device for locking the rotary handle at least in the OFF position when engaged, and a POFF device for preventing the rotary handle to be rotated and/or fixed in OFF position when activated. The electronic switching device further includes a locking coulisse, movably arranged at the electronic switching device and arrangeable in at least a first position, a second position and a third positions with respect to the housing of the electronic switching device. The locking coulisse is configured for allowing an engagement of the handle locking device and the POFF device in the first position, locking the housing door in the second position and blocking the activation of the handle locking device in the third position.

A receiving module is disclosed for building into a switching cabinet, with a primary circuit mating contact element. To improve the coupling of a power switch, especially a low-voltage power switch, to a receiving module, it is proposed in at least one embodiment that the receiving module also has a communication mating contact element, wherein the receiving module can directly receive a power switch, so that a primary circuit contact element of the power switch is directly electrically-conductively connected to the primary circuit mating contact element and a communication contact element of the power switch is directly electrically-conductively connected to the communication mating contact element, wherein the communication mating contact element is arranged in relation to the primary circuit mating contact element such that, in a first receiving position of the power switch in the receiving module the communication contact element is electrically-conductively connected to the communication mating contact element and the primary circuit mating contact element is not electrically-conductively connected to the primary circuit contact element and in a second receiving position of the power switch in the receiving module the primary circuit mating contact element is directly electrically-conductively connected to the primary circuit contact element and the communication mating contact element is directly electrically-conductively connected to the communication contact element.

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.
