BL0214 Green Glass Gold Pin Water Meter 2*14mm Normally Open Reed Switch

What is a normally open reed switch?

The normally open reed switch is composed of two reeds made of both magnetic and conductive materials (usually iron-nickel alloy) and sealed in a glass tube in parallel, leaving a certain gap between the two reeds (usually 0.2 mm) Left and right), when the bar-shaped permanent magnet approaches the reed tube in parallel, the two reeds are magnetized and attracted to each other, and the contacts are closed. When the permanent magnet is far away, the contact opens again.
