Maximising the reliability of Reed Relays in your design

If used correctly, a Reed Relay is a superbly reliable device.

The switch contacts are hermetically sealed, so do not suffer from oxidisation 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.

Pickering Electronics has written a concise technical guide with the aim to help you to maximise the reliability of your design.
