The Multiquip CH15516 Water Switch STH 55 4020TF is a genuine OEM component designed for STH55 series equipment. Sourced directly from Multiquip, this switch is built to the same specification as the original part, ensuring correct operation within the machine's water system. Verified to fit STH55 models, the part is the correct replacement when your original switch shows signs of failure or inconsistent performance.
Key Features
- OEM-Rated Switching Specification — Engineered to the exact electrical and pressure thresholds required for proper water system control, so the switch activates and deactivates at the correct set point every time.
- Direct Drop-In Replacement — Matches the original mounting configuration and connector interface of the STH55, allowing straightforward installation without adapters or modifications to existing hardware.
- Confirmed STH55 Fitment — Verified compatibility with STH55 series machines; use part number CH15516 to confirm the correct application before ordering.
- Consistent Water System Response — A properly functioning water switch ensures the water delivery circuit engages and disengages on demand, protecting downstream components from dry-run conditions or uncontrolled flow.
- Electrical Safety Compliance — As a switching component in a water-adjacent circuit, the part is built to withstand the moisture exposure and load cycling inherent to this application, reducing the risk of electrical faults.
The water switch on the STH55 controls the activation and shutoff of the machine's water supply circuit. It monitors system conditions and signals the water flow to engage or cut off based on operational demand, protecting the equipment from running dry or flooding unintentionally. When the switch fails, the water system may not respond correctly — leading to erratic water delivery, potential overheating of water-cooled components, or unintended continuous flow that can affect performance and service life.
