Technical Guide to Reed Relays
If used correctly, a reed relay is a superbly reliable device. The switch contacts are hermetically sealed, so do not suffer from oxidization or contamination in the same way as an open electromechanical relay. Although in reality, relays are often considered slightly mundane and little thought is given to them which sometimes leaves them vulnerable. This guide will help you to maximize the reliability of your design whilst switching with reed relays.
