Operation

In general four different magnet approaches are known when using permanent magnets.

1. One magnet pole faces Reed Switch providing two operations max. when moving on X-axis. Minimum movement of magnet over switch center provides smallest possible switching differential.

 

2. Magnet parallel to longitudinal axis of switch.

 

Approaching magnet vertically to switch on Y-axis provides one operation only. Driving magnet over full length of switch (X-axis) may result in up to three operations. Minimum movement of magnet over switch center provides smallest possible switching differential.h.

3. Rotation Switch operation by rotation of magnet. This gives two operations per complete rotation.

4. Operation of switch by shielding. This method requires a permanently opposite location of magnet and switch. The switch is held closed continuously and will release only if magnet flux is removed by means of ferro-magnetic shield.
