The TPA11CGRA204 is a mechanical tactile pushbutton switch from the TPA series designed for surface-mount printed circuit board applications. It features a single pole-single throw (SPST) configuration with a contact rating of 0.4VA and gold-plated copper alloy contacts for reliable electrical performance. The switch employs a right-angle mount orientation with an extended round red nylon actuator measuring 3.84 mm in length, housed in a thermoplastic LCP case body. It is rated for through-hole mounting with printed circuit board termination and operates across a standard industrial temperature range. This switch is commonly used in consumer electronics, industrial control panels, and portable devices where compact tactile feedback and low-power switching are required.
