Navigating the Extremes: Challenges of Piezo Switches in Boiling Water
Piezo switches encounter three primary challenges when immersed in boiling water:
- Thermal Shock – Abrupt and extreme temperature fluctuations can induce cracking in ceramic elements or cause housing deformation.
- Seal Degradation – Elevated temperatures significantly accelerate the aging process of gaskets and the breakdown of bonding adhesives.
- Continuous Immersion – Extended periods of water contact impose considerable stress on the internal electronic components.
Understanding the 75 °C Threshold: Limitations of Standard Piezo Switches
Manufacturers typically establish a 75 °C operational limit for standard models to mitigate the following critical risks:
- Epoxy Softening – Bonding adhesives experience a significant reduction in mechanical strength when temperatures exceed 80 °C.
- Ceramic Depolarization – Piezoelectric elements can irreversibly lose their sensitivity and functionality if exposed to temperatures above their critical Curie temperature.
- O-Ring Compression Set – Elastomer seals are prone to compression set, leading to leakage under prolonged thermal stress.
Adhering to these design constraints is paramount for safeguarding the long-term reliability and performance of piezo switches in conventional industrial environments.

IP Ratings Explained: Ensuring Piezo Switch Performance in High-Temperature Liquids
IP68 and IP69K certifications represent critical international standards for ingress protection against dust and water. They precisely quantify a switch’s capacity to withstand prolonged submersion and aggressive high-pressure, high-temperature washdowns—essential criteria for control devices operating in liquid-intensive environments.
Contact Langir for Custom Piezo Switches
Decoding IP68: Comprehensive Water and Dust Protection
An IP68 rating signifies that a switch is completely dust-tight and engineered to endure continuous submersion beyond 1 meter—commonly specified as 1.5 meters for a duration of 30 minutes. This superior level of sealing effectively shields all internal components from both particulate matter and moisture ingress, making it indispensable for submerged or perpetually wet operational environments.
The Power of IP69K: Withstanding High-Pressure, High-Temperature Washdowns
IP69K certification involves subjecting devices to intense 80 °C water jets, delivered at 80–100 bar pressure from various angles. Successful completion of IP69K testing unequivocally confirms that a switch’s seals and housing materials are robust enough to withstand the most aggressive cleaning protocols, a common requirement in demanding food processing and medical sterilization applications.
IP69K and Boiling Water: Understanding the Limits
While IP69K-rated piezo switches are engineered to withstand brief exposure to hot, pressurized water up to 80 °C, it is crucial to note they are not certified for continuous immersion in 100 °C boiling water. For applications demanding repeated sterilization cycles in boiling water, a bespoke design incorporating advanced ceramics and specialized high-temperature seals is absolutely essential to ensure sustained long-term performance.
