Are piezo switches the ideal solution for automatic car wash systems?

Automatic car wash systems rely on Human-Machine Interfaces (HMIs) to deliver a seamless customer experience. These interfaces must not only be functional but also durable and user-friendly in the face of challenging conditions. From managing water, detergent, and chemicals to interacting with users, these machines face a range of environmental hurdles that can affect the performance of the HMI.

First, the operating environment itself presents a significant challenge. Exposure to water, humidity, and extreme temperatures can impact the reliability of the HMI components. Materials used need to be resistant to corrosion and able to withstand constant exposure to harsh elements, like water sprays and chemicals. Additionally, the machine’s user interface needs to be accessible to a wide variety of customers, some of whom may not be familiar with complex technology. Designing an interface that is simple, intuitive, and easy to use for all customers is key to ensuring that the car wash system operates smoothly.

For public-facing components, switches must withstand physical damage and constant handling. APEM piezo switches are constructed with screw-machined metal housings and a solid-state design, making them resistant to impacts, vandalism, and wear. Their durability ensures reliable operation over time, even in car wash systems’ high-traffic environments. The design prevents wear from moving parts, further extending their lifespan while maintaining consistent performance.
