How Mechanical Vacuum Switches Work
Mechanical vacuum switches operate based on a diaphragm or bellows mechanism that senses changes in pressure. When a specific vacuum level is reached, the change in pressure causes the diaphragm to move, triggering a mechanical switch that opens or closes an electrical circuit. This action can control processes such as pumps and fans, enabling precise vacuum management.
