The **WRS-532-R** is a specific model of a **Miniature Rocker Switch**. These components are widely used in power distribution for small appliances, industrial controls, and automotive electronics to manually open or close an electrical circuit. ### Technical Specifications The "WRS" series typically follows standardized electrical ratings. Below are the common specifications for this part number: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Rocker Switch | | **Circuit Function** | SPST (Single Pole Single Throw) | | **Switching Action** | ON - OFF | | **Current Rating** | 10A @ 125VAC / 6A @ 250VAC | | **Contact Resistance** | 50mΩ Max | | **Insulation Resistance** | 100MΩ Min at 500VDC | | **Dielectric Strength** | 1500VAC for 1 minute | | **Operating Temperature** | -25°C to +85°C | --- ### Key Electronic & Physical Parts #### 1. The Actuator (Rocker) This is the external plastic part that the user presses. In the "R" variant (WRS-532-**R**), the "R" often signifies a **Red** actuator or a specific **Rectangular** shape. It pivots on a central axis to change the state of the internal contacts. #### 2. Terminals (Quick Connect) The switch features silver-plated copper alloy terminals. Usually, these are **0.187" (4.8mm)** or **0.250" (6.35mm)** quick-connect spade terminals, allowing for easy wiring without the absolute necessity of soldering. #### 3. Moving Contact (The Bridge) Inside the housing, there is a metallic leaf or "bridge." When the rocker is pressed to the "ON" position, this bridge snaps down to connect the two stationary terminals, completing the circuit. #### 4. Housing/Casing Made from **Nylon 66 (UL94V-2)**, the housing is designed for "Snap-in" mounting. This means the electronic part can be pushed into a rectangular panel cutout and held in place by plastic tension wings without screws. --- ### Circuit Diagram Representation Since it is an **SPST** switch, the internal logic is simple: ```text Terminal 1 (Input) ----/ ---- Terminal 2 (Output) (Switch) ``` ### Common Applications * **Power Strips:** Used as the primary master power toggle. * **Computer Peripherals:** External hard drive enclosures or monitors. * **Small Appliances:** Coffee makers, vacuum cleaners, and desktop lamps. * **DIY Electronics:** Used as a main power cutoff for hobbyist projects.
