Hayward PRESSURE SWITCH

the Hayward Pressure Switch is a vital safety and operational component designed to monitor the hydraulic flow within pool heaters and salt chlorine generators, ensuring that the equipment only functions when there is sufficient water movement. Constructed with a durable plastic housing and a sensitive internal diaphragm, this switch detects the physical pressure exerted by the pump; when the flow reaches a specific threshold (typically measured in pounds per square inch), it closes an electrical circuit to allow the heating or sanitizing process to begin. This mechanism serves as a critical fail-safe, preventing "dry-firing" or overheating of the internal elements by immediately cutting power if the pump fails, a valve is closed, or the filter becomes excessively clogged. Engineered to resist the corrosive effects of salt and chlorine, it features high-conductivity metal terminals and a threaded fitting for easy integration into the plumbing manifold. For shipping and logistical purposes, the estimated weight of the Hayward Pressure Switch is approximately 0.4 pounds in its retail protective packaging, while the actual dry weight of the switch assembly itself is roughly 0.2 pounds.
