E-Switch provides a recommended PCB layout and land pattern in their application notes, which can be found on their website. The recommended land pattern is a 4-pad layout with a 1.5mm x 1.5mm pad size and a 0.5mm spacing between pads.
To ensure reliable switch operation in high-vibration or high-shock environments, it's recommended to use a switch with a higher operating force (e.g., 260gf or higher) and a shorter travel distance (e.g., 0.5mm or shorter). Additionally, consider using a switch with a built-in debounce mechanism or implementing external debouncing circuitry.
The maximum current rating for the RD111C1121 is 50mA at 12VDC. Exceeding this rating may lead to premature switch failure or reduced lifespan.
The RD111C1121 is rated for operation up to 85°C (185°F). While it can tolerate short-term exposure to higher temperatures, prolonged exposure above 85°C may affect switch performance and lifespan.
Use a soft, dry brush or a lint-free cloth to gently remove any debris or contaminants from the switch. Avoid using harsh chemicals, solvents, or abrasive materials that may damage the switch or its components.
