An insertion device may include a base adapted to be carried by a patient, and a housing attached to the base, the housing having a fluid connector arranged for movement relative to the base. A pair of interactive elements including a first interactive element may be supported on the base and a second interactive element supported on the housing at a location to be interactable with the first interactive element when the fluid connector is moved to a predetermined position. Circuitry may be configured to detect an interaction between the first interactive element and the second interactive element when the fluid connector is in the predetermined position, the circuitry configured to provide a signal or a change in state in response to detecting the interaction between the first interactive element and the second interactive element.
