The **M2BS2-162-R** is a specific model of a **Miniature Pushbutton Switch**, typically manufactured by companies like **Nidec Copal Electronics**. It belongs to the M2 series, which is designed for high-density mounting on printed circuit boards (PCBs). ### Technical Specifications Summary | Feature | Specification | | :--- | :--- | | **Switch Type** | Pushbutton (Momentary) | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Contact Rating** | 0.05A @ 48V AC/DC (Logic Level) | | **Terminal Type** | Right-Angle PC Terminals | | **Operating Force** | 1.5 ~ 4.5 N | | **Mechanical Life** | 30,000 Cycles minimum | | **Operating Temperature** | -25°C to +70°C | --- ### Key Features and Component Breakdown #### 1. Contact Mechanism The "S2" in the part number often refers to the **Snap-action mechanism**. This provides tactile feedback to the user (a "click" feel) and ensures a quick, decisive transition between electrical states, which reduces arcing and contact wear. #### 2. DPDT Configuration As a **Double Pole Double Throw** switch, it controls two independent circuits simultaneously. Each "pole" has a common terminal that can connect to one of two different output terminals depending on whether the button is pressed or released. #### 3. Mounting Style (Right-Angle) The **-R** suffix typically denotes a **Right-Angle** orientation. This means the actuator (the button) sticks out horizontally relative to the PCB. This is ideal for edge-mounting on devices where the user interacts with the switch from the side of the housing. #### 4. Gold-Plated Contacts These switches generally use gold-plated contacts. This makes them highly reliable for "dry circuit" or low-power applications (logic levels), as gold prevents oxidation that would otherwise interfere with the signal in low-voltage electronics. --- ### Common Applications * **Telecommunications:** Signal switching in networking hardware. * **Instrumentation:** Mode selection in hand-held measuring tools. * **Consumer Electronics:** Power or reset buttons in compact devices. * **Industrial Controls:** Low-level logic switching on control panels. ---
