Reed Switches

Littelfuse Reed Switches are ideal for battery-powered applications and automotive safety products. Reed switches have two ferromagnetic blades contained within a tubular glass envelope that is hermetically sealed at each end. Switches are activated by a permanent magnet or an electromagnet, and the reed switch and magnetic field combination is commonly known as the "magnetic circuit."
