Reed Switch Test Setup

For the Reed switch, the test setup is fundamentally the same as for the hall effect switch test. The device is already mounted on a pcb board so there is no need to implement onto a separate breadboard. Instead of using an LED for detection indication, a multimeter with a continuity function is used along with alligator clip test leads that are clamped to each respective end of the Reed switch. While no magnet is present in range of the Reed switch, there will be no continuity between the leads of the Reed switch. Once a magnet comes close enough to close the Reed switch, continuity is detected through an audible tone from the multi meter. The distance of detection can then be measured and recorded for later analysis.
