The 19mm anodized aluminum piezo switch push button boasts a waterproof IP68 rating, making it ideal for outdoor applications. With an operating humidity range of 10-99%, it can function in various conditions. The switch has a wide input voltage range of 5-24V AC/DC and a maximum input current of 2A. Its contact resistance is ≤100Ω, and the operating force is between 2 to 6N. It offers over one million switch life cycles for durability. The switch's crust material is anodized aluminum, providing strength and corrosion resistance. This 2-wire lead piezo switch is not polarity sensitive, allowing for flexible wiring configurations. Based on the FET technology, the piezoelectric element generates a charge that activates the integrated semiconductor device, turning the switch "on." When the voltage pulse dissipates, the FET turns off. The piezoelectric effect utilizes force-induced stress to generate an electric charge. In piezo switches, compressive pressure causes the disc-shaped piezo element to bend slightly like a drumhead, generating a brief "on" pulse that can be adjusted with additional circuitry. Piezo switches offer advantages over mechanical switches, including no moving parts for increased durability and easy sealing for weatherproofing.
