A reed switch (46) in a solid plastic body (60) is positioned by a clip adjacent to a fluid container. Change in fluid level opposite the reed switch moves a magnet (38) connected to a float, turning the reed switch on or off. Glass filled polyester is injected into a die which surrounds the reed switch supported on electrical plug blades (42, 44). The reed switch has high stiffness leads (48, 50) positioned on the blades, and is oriented within the mold so the injected plastic flows along the glass tube of the reed switch, minimizing stresses on the reed switch, which could result in the reed switch becoming crack and/or broken. The molded plastic body incorporates an integrally formed clip arm (70) which functions to position and hold the plastic body onto a larger structure. The magnet and float may move in a tube, may pivot, or slide along rails in response to a change in fluid level.
