The **M2TT-35-R/BL** is a specialized electronic component primarily categorized as an **SMD (Surface Mount Device) Tactile Switch**. These components are frequently used in consumer electronics, automotive controls, and industrial interfaces where space is limited and tactile feedback is required. Below is a breakdown of its technical specifications, construction, and applications. --- ### 1. Technical Specifications This table outlines the typical electrical and mechanical properties for this series: | Parameter | Value/Description | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Operating Force** | Typically 160gf to 250gf (Gram-force) | | **Contact Rating** | 50mA @ 12V DC | | **Actuator Height** | 3.5mm (indicated by the "35" in the part number) | | **Color Code** | Black (BL) Actuator | | **Orientation** | Right Angle (indicated by the "R") | --- ### 2. Key Features and Construction * **Right Angle Design (R):** Unlike standard top-actuated switches, the "R" designation signifies a side-actuated or right-angle orientation. This allows the button to be pressed from the edge of a PCB, making it ideal for side-mounted buttons on smartphones or controllers. * **Tactile Feedback:** The switch utilizes a metal dome contact mechanism. When pressed, it provides a distinct "click" sound and physical sensation, confirming to the user that the connection has been made. * **Termination:** It features "Gull-wing" or J-lead terminals designed for automated SMT pick-and-place assembly and reflow soldering. * **Durability:** Most switches in this class are rated for 50,000 to 100,000 cycles, depending on the specific manufacturer's tolerances. --- ### 3. Application Use Cases The M2TT-35-R/BL is commonly integrated into the following devices: 1. **Consumer Electronics:** Power buttons on cameras, volume rockers on tablets, and Bluetooth headset controls. 2. **Automotive:** Dashboard controls, steering wheel buttons, and key fobs. 3. **Medical Devices:** Handheld diagnostic tools and portable monitors. 4. **Computing:** Reset buttons on motherboards or peripheral input devices. --- ### 4.
