The **RAR-10-R-T** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Tactile Switch**. These components are widely used in consumer electronics to provide a "clicky" physical interface for user input. Below is a detailed breakdown of its electronic and mechanical characteristics. --- ## 1. Technical Specifications This component is designed for low-power signal switching. The general specifications for the RAR series (often manufactured by companies like Multicomp or similar electronic hardware brands) are as follows: | Feature | Specification (Typical) | | :--- | :--- | | **Type** | Tactile Switch | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Actuation Direction** | Right Angle (Side Actuated) | | **Contact Rating** | 50mA @ 12V DC | | **Operating Force** | 160gf (Grams-force) | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Travel** | 0.25mm | | **Life Cycle** | ~100,000 Cycles | --- ## 2. Key Features ### A. Right Angle Orientation The "R" in the part number often signifies **Right Angle**. Unlike standard vertical switches, this component is mounted on the edge of a PCB, allowing the user to press it from the side. This is essential for devices like volume buttons on smartphones or power buttons on the sides of handheld gadgets. ### B. Tactile Feedback It provides a "snap" or "click" sensation when pressed. This is achieved via an internal metal dome that collapses under a specific force (160gf) and springs back when released, completing and then breaking the electrical circuit. ### C. Termination Style (T) The "T" typically indicates the packaging or termination style, often referring to **Tape and Reel** packaging, which is necessary for automated pick-and-place machines during high-speed PCB assembly. --- ## 3. Common Applications * **Consumer Electronics:** Wearables, remote controls, and digital cameras. * **Telecommunications:** Handsets and networking equipment reset buttons. * **Industrial:** Interface panels where space is limited on the vertical axis. * **Computing:** Peripheral devices like mice or keyboards (side buttons). --- ## 4. Typical Pin Configuration Since it is a **SPST-NO** switch, it usually features four pins (two pairs internally connected). When the button is pressed, the connection between the pins is closed. ```text [ Pin 1 ]-------[ Pin 2 ] | | (Button Mechanism) | | [ Pin 3 ]-------[ Pin 4 ] ``` *Note: In a normally open state, current does not flow until the actuator is depressed.*
