1. An on-body injector comprising:
a reservoir filled or configured to be filled with a drug;
a cannula;
a drive operable to move the drug out of the reservoir;
a proximity sensor having a first sensor state when the proximity sensor is not in contact with skin of a patient and a second sensor state when the proximity sensor is in contact with the skin of the patient, wherein the proximity sensor is configured to output at least one electrical signal as a result of changing from the first sensor state to the second sensor state;
a lock having a first position to prevent the drive from moving the drug out of the reservoir when the proximity sensor is in the first sensor state and the lock having a second position permitting the drive to move the drug out of the reservoir when the proximity sensor is in the second sensor state, wherein the lock is operably coupled to the proximity sensor such that the proximity sensor changing from the first sensor state to the second sensor state causes the lock to move from the first position to the second position; and
an actuator configured to move the lock between the first position and the second position.
