The **RM-08-T-R** is a specific model of a **DIP Switch**, typically used in electronics to set configurations or select modes on a printed circuit board (PCB). --- ### 1. Key Technical Specifications The part number usually decodes into specific physical and electrical characteristics. Below is a breakdown of the standard specifications for this component: | Feature | Specification | | :--- | :--- | | **Component Type** | DIP Switch (Dual In-line Package) | | **Number of Positions** | 8 Positions (8 individual switches) | | **Actuator Style** | Raised (Slide Type) | | **Mounting Type** | Through-Hole (THT) | | **Contact Material** | Gold Plated (for high reliability) | | **Current Rating** | 25mA at 24VDC (Switching) / 100mA at 50VDC (Non-switching) | | **Pitch** | 2.54mm (0.1 inch) | --- ### 2. Part Number Breakdown While nomenclature varies slightly by manufacturer (such as Kingbright, Multicomp, or others), the code generally follows this logic: * **RM**: Series designation (often indicating "Standard" or "Raised" slide type). * **08**: Indicates **8 individual switches** within the single housing. * **T**: Indicates the packaging type, usually **Tube** packaging for automated assembly. * **R**: Often indicates **Red** housing color or **RoHS** compliance depending on the specific vendor datasheet. --- ### 3. Internal Components & Materials To understand the "electronic parts" inside the RM-08-T-R, we look at its construction: 1. **Housing:** Made of high-temperature PBT or Nylon plastic (UL94V-0 rated) to withstand soldering heat. 2. **Actuators:** The white sliding pieces used to manually toggle the circuit. 3. **Base Contacts:** Stationary metal pins (usually copper alloy with gold over nickel plating) that are soldered to the PCB. 4. **Wiping Contacts:** The moving internal metal part that creates a bridge between the two stationary pins when "ON." --- ### 4. Common Applications * **Address Setting:** Assigning a unique ID to a device on a network (e.g., RS-485 or DMX). * **Configuration:** Selecting hardware options without needing to re-program software. * **Security:** Setting a manual pin code for garage door openers or remote controls.
