A pneumatic switch is a reliable and safe control device commonly used in spa, bathtub, and pool systems to operate pumps, blowers, and lights without electrical contact. It functions by using air pressure instead of electricity, making it ideal for wet environments where electrical safety is crucial. When the user presses the connected air button, a burst of air travels through an air hose to the switch mechanism, triggering the connected equipment on or off. This isolated, contact-free operation greatly reduces the risk of electrical shock, enhancing user safety around water. Pneumatic switches are typically mounted remotely from the equipment, allowing for flexible installation and ease of use. They are available in momentary or latching (on/off) configurations to suit various control needs. Durable and low-maintenance, these switches are widely used in spas, hot tubs, and whirlpool systems. Their simple design and mechanical reliability make them a trusted choice for both residential and commercial applications.
