### Overview: M2TS-70-R/BL The **M2TS-70-R/BL** is a specialized high-performance tactile switch, typically categorized within the **M2 series** of miniature toggle or pushbutton switches. It is commonly used in industrial controls, telecommunications, and high-reliability consumer electronics. --- ### Technical Specifications Below are the primary electronic and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Switch Type** | Pushbutton / Tactile Switch | | **Mounting Type** | Through-hole (Right Angle / Vertical options) | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Contact Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Electrical Life** | 50,000 to 100,000 Cycles | | **Actuator Color** | Red (**-R**) / Black (**-BL**) | | **Operating Force** | ~1.5N to 2.5N | --- ### Key Electronic Components & Materials 1. **Contact Mechanism:** * **Gold-Plated Contacts:** Most models in this series use gold over nickel plating. This ensures high conductivity and prevents oxidation, making it ideal for low-voltage/low-current logic circuits. 2. **Sealing (Environmental Protection):** * The "70" designation often refers to the **IP67 rating** or equivalent sealing. This means the internal electronic contacts are protected against dust ingress and temporary immersion in water. 3. **Terminal Leads:** * Constructed from brass with tin plating for ease of soldering. The "R" usually indicates a **Right-Angle** orientation for PCB mounting. 4. **Housing:** * Made from high-temperature Polyamide (Nylon) or Diallyl Phthalate (DAP), allowing the part to withstand wave soldering temperatures. --- ### Part Number Breakdown | Segment | Meaning | | :--- | :--- | | **M2** | Series designation (Miniature/Subminiature) | | **TS** | Tactile Switch / Toggle Subminiature | | **70** | Specific Model / Dimensions / Rating code | | **R** | Right Angle PCB Mounting | | **BL** | Button/Actuator Color (Black) | --- ### Typical Applications * **Medical Equipment:** Due to the high cycle life and reliability. * **Handheld Instruments:** Used where space is limited and a right-angle interface is needed. * **Network Hardware:** Reset buttons or mode selection switches.
