What is a Vacuum switch?

A vacuum switch is a type of pressure switch designed to operate in vacuum or low-pressure environments. It is used to turn a system on or off when the pressure reaches a preset vacuum level. While standard pressure switches are designed for atmospheric or high-pressure conditions, a vacuum switch is specifically designed to detect pressure changes in vacuum systems or low-pressure environments. Vacuum switches are widely used for monitoring, controlling, and protecting vacuum systems. The vacuum switch uses an internal pressure sensor to detect the vacuum level, and based on the result, it operates the switch. Common applications include starting or stopping a vacuum pump, triggering alarms when the vacuum chamber pressure falls below a specified level, or activating safety devices in the event of excessive low pressure. Due to their high sensitivity, vacuum switches can detect even the slightest pressure changes, allowing for precise control in vacuum-related systems.

Some examples of devices that use vacuum switches are vacuum pumps, vacuum packaging machines, vacuum systems in electronic devices, and semiconductor manufacturing equipment. In these applications, maintaining a consistent vacuum level is crucial, and vacuum switches play a critical role in ensuring system safety and performance by preventing pressure-related issues.

Application of Vacuum switch

✅Vacuum Pumps
Vacuum switches are used to control the operation of vacuum pumps by monitoring the pressure levels. When the vacuum pressure falls below a set threshold, the switch can trigger the pump to start or stop, ensuring optimal operation.
✅Vacuum Packaging Machines
In food packaging, vacuum switches help monitor and control the vacuum level inside packaging machines. When the pressure drops too low or too high, the switch activates safety mechanisms to prevent incorrect packaging.
✅Semiconductor Manufacturing
In semiconductor fabrication, vacuum switches are used in the vacuum chambers to maintain a specific pressure range. If the vacuum pressure exceeds or drops below the desired level, the switch can trigger alarms or halt the process to protect the equipment.
✅Medical Equipment (Vacuum Systems)
In medical equipment like suction machines, vacuum switches are used to monitor the vacuum pressure in suction systems. If the pressure is too high or low, the switch can ensure the system operates within safe parameters.
