This glass reed switch is a normally open type with a dimension of 14 x 2mm. It is compact in size and light weight allowing it to be installed in extremely limited space, very suitable for miniaturization of circuits. It doesn't use the sliding element, thus, metal fatigue phenomenon will not appear, effectively eliminating mechanical failure and lifespan.
