A waterproof pressure switch with a terminal block that uses a robust aluminum die-cast cover for the exterior. The SPS-18F is available
when the opening/closing pressure difference needs to be 1/2 . Equipped with a 3P terminal block so that a cap tire cord with an outer diameter of φ7 to φ11 can be wired.
