Ensuring spa safety and comfort with pneumatic, air and pressure switches

When it comes to spa applications, safety and user experience are key considerations. One of the most effective ways to ensure both is by using pneumatic switches in conjunction with air or pressure switches. These switches provide a reliable and safe method for users and operators to control spa features like jets, lighting, and even emergency alarms while avoiding the risks associated with electrical systems in wet and high-humidity environments.

The function of air-activated switches in spas

Pneumatic switches are an ideal choice for spas because they operate without electricity, eliminating the risk of electric shock. Found in equipment such as jacuzzis, whirlpool baths, saunas, floatation tanks and multi-jet showers, these switches use air pressure to activate various functions, instead of relying on direct electrical connections.

With a simple press of a button, a pneumatic switch sends an air signal through tubing to a remotely located control unit where the air or pressure switch is located. This allows spa users or operators at home or in a commercial spa setting to turn on jets, adjust lighting, and control other features without coming into contact with electrical components that could pose a serious safety hazard.

In spa systems, long tubing lengths are essential for safely transmitting air pressure signals over a distance. Highly sensitive pressure switches must be  used to achieve maximum tube length, with the HPS-500 miniature pressure switch, for example, having a pressure range that starts at just 0.25 mbar.

Panic alarms and sauna safety

In addition to controlling spa functions, pneumatic and air or pressure switches are also used in panic alarms and sauna safety systems. Emergency situations can arise unexpectedly, making it essential to have a reliable alarm system in place. Sauna alarms allow users to call for help in case of overheating or distress, ensuring safety without the risk of electrical shock.
