Magnetic and mechanical design of ultraminiature reed switches

The miniaturization limit of the reed switch with respect to its magnetic and mechanical properties is discussed. Assuming that the contact rating, the switching current and voltage, the carry current, and the breakdown voltage decrease, it was found that the ultraminiature reed switch with a glass inner diameter of 1.0 mm and a glass inner length of 4.0 mm can be mass produced using existing process technology.<
