The **RMR-04-R** is a specific type of electronic component, typically identified as a **4-position, right-angle, surface-mount (SMT) DIP switch**. These components are widely used in electronics to set binary configurations or device addresses manually. --- ### Technical Specifications Below are the typical technical characteristics associated with the RMR-04-R series: | Parameter | Specification | | :--- | :--- | | **Number of Positions** | 4 | | **Actuator Type** | Recessed Rocker or Slide | | **Mounting Type** | Surface Mount (SMT) / Right Angle | | **Pitch** | 2.54mm (0.1 inch) or 1.27mm (Half-pitch) | | **Contact Rating** | 25mA at 24VDC (Switching) | | **Insulation Resistance** | 100MΩ Minimum | | **Operating Temp** | -40°C to +85°C | --- ### Key Features 1. **Right-Angle Orientation:** The "R" in the suffix usually denotes a **Right-Angle** configuration. This means the actuators are accessible from the side of the PCB rather than the top, which is ideal for side-panel access in slim enclosures. 2. **Gold-Plated Contacts:** Most RMR series switches utilize gold plating on the contacts to prevent oxidation and ensure high reliability over the component's lifespan. 3. **Reflow Soldering Compatibility:** Designed with high-temperature plastics (like LCP or PPS), these parts can withstand the heat of infrared (IR) or convection reflow soldering processes. --- ### Internal Structure & Operation The RMR-04-R operates as a set of four independent **SPST (Single Pole Single Throw)** switches. * **Logic 0:** Switch in the "OFF" position (Open circuit). * **Logic 1:** Switch in the "ON" position (Closed circuit). #### Typical Pinout Diagram ```text TOP VIEW (Right Angle) ___________________ | [1] [2] [3] [4] | <-- Actuators |___________________| | | | | | <-- SMT Leads (Output) [Common/Input Side Hidden Underneath] ``` --- ### Common Applications * **Industrial Controls:** Setting Modbus or CAN bus node IDs. * **Consumer Electronics:** Configuring WiFi channels or mode selections. * **Computer Peripherals:** Setting master/slave configurations on legacy hardware. * **Security Systems:** Coding remote controls or sensors.
