The Stopwatch node measures provides two modalities to determine how it should start counting time which are specified by the Trigger policy property:

• Switch The Stopwatch starts counting time when the Input connector value goes to 1, it pauses when the Input value goes to 0. Whenever the node pauses, it sends the time the Input value has been 1 to the Partial time connector and the total counted time to the Total time connector.
• Toggle The Stopwatch starts counting when it receives the first rising edge on the Input connector, all the other times it receives a rising edge it sends the time passed between the current rising edge and the previous one to the Partial time connector, and the total counted time to the Total time connector.

When the Reset connector value is 1, the node stops counting the time and sends 0 to both Partial time and Total time, it will start counting again only after the Reset value goes to 0.
