1. A method of inserting an analyte sensor into a subject, the method comprising:

  • positioning a distal surface of an insertion assembly on skin of the subject such that an adhesive layer adheres to the skin, the insertion assembly comprising a spring in a loaded position and an interior; and

    pressing a button of the insertion assembly in a first lateral direction toward the interior of the insertion assembly,wherein pressing the button releases the spring from the loaded position such that the spring moves a sliding member lengthwise along a length of a track in the insertion assembly, wherein the length of the track is oriented in a second lateral direction different from the first lateral direction,wherein movement of the sliding member along the length of the track causes an actuator to advance in a distal longitudinal direction, wherein advancement of the actuator causes advancement of a sharp and the analyte sensor in the distal longitudinal direction,wherein the sliding member applies a force on the actuator in a proximal longitudinal direction after the sharp and the analyte sensor have been advanced in the distal longitudinal direction, andwherein the distal longitudinal direction and the proximal longitudinal direction are defined along an insertion axis.
