Description of operation
When the pressure exceeds the upper change-over point (which is set in the scale on the right), the contacts switch from 1-2 to 1-3. When the pressure falls below the lower change-over point (which is set in the scale on the left), the contacts switch from 1-3 to 1-2. The vibration-proof snap-action switch has a pre-loaded spring that only activates the change-over mechanism when the change-over point has been reached. As a result, the contact force is maintained up to the change-over point even when the switch is activated very slowly.
