Most studies evaluating the performance of quantum switches have primarily relied on mathematical models. While some have considered switch simulation, they have largely overlooked the impact of concurrent entanglement requests, a crucial factor in practical switch design and optimization. This work addresses this gap by developing a NetSquid-based simulator of a quantum switch that supports concurrent entanglement requests. We validate the simulator against a well-established capacity model and present preliminary findings for concurrency scenarios that have not yet been analytically explored, offering novel insights into quantum network performance research.
