The **CSS-233** is a commonly used **Slide Switch** found in electronic circuits, particularly in consumer electronics, toys, and small appliances. It is a sub-miniature, surface-mount (SMD) or through-hole component designed to act as a physical toggle for power or signal routing. --- ### Technical Specifications The following table outlines the typical electrical and physical characteristics of a CSS-233 series switch: | Parameter | Specification (Typical) | | :--- | :--- | | **Circuit Type** | SPDT (Single Pole Double Throw) | | **Switch Function** | On-On / 2-Position | | **Current Rating** | 100mA to 300mA | | **Voltage Rating** | 4V DC to 12V DC | | **Contact Resistance** | < 70mΩ | | **Insulation Resistance** | > 100MΩ (at 500V DC) | | **Operating Life** | 10,000 cycles | | **Actuator Height** | 2.0mm to 3.0mm | --- ### Internal Construction and Parts The CSS-233 consists of several precision-engineered electronic and mechanical parts: 1. **Actuator (The Knob):** Usually made of high-temperature plastic (PA66 or POM). It is the part the user slides to change the circuit state. 2. **Contact Terminal:** Typically made of copper alloy with **Silver or Gold plating** to ensure high conductivity and prevent oxidation. 3. **Moving Contact (Slider):** A small metal leaf that bridges the connection between the common pin and the output pins. 4. **Base/Housing:** A heat-resistant thermoplastic frame that holds the terminals in place and protects the internal mechanism. 5. **Terminals:** The pins used to solder the component to a PCB. CSS-233 usually features 3 pins (1 Common, 2 Outputs). --- ### Pin Configuration (SPDT) In a standard CSS-233, the three pins are arranged linearly: ```text [ Actuator ] /--------------\ | [1] [2] [3]| <-- Solder Terminals \--------------/ ``` * **Pin 2 (Center):** The Common (COM) terminal. * **Pin 1 & 3:** The output terminals. When the slider is moved left, Pin 2 connects to Pin 1. When moved right, Pin 2 connects to Pin 3. --- ### Common Applications Due to its small footprint, the CSS-233 is frequently integrated into: * **Battery-powered devices:** To turn the power ON or OFF. * **Circuit Mode Selection:** Switching between different modes (e.g., Mono/Stereo, Gain High/Low). * **Reset Switches:** For handheld gaming devices or remote controls.
