The **TCS-41-R** is a specific electronic component typically identified as a **tactile switch** (or tact switch). These are momentary push-button switches commonly used in low-power signal switching applications. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications Tactile switches like the TCS-41-R are designed for surface mount or through-hole PCB integration. The "R" usually denotes a specific packaging type (like Tape & Reel) or a right-angle orientation, depending on the manufacturer's series. | Feature | Typical Specification | |:---|:---| | **Switch Type** | Momentary (Normally Open) | | **Contact Rating** | 50mA @ 12V DC | | **Insulation Resistance** | 100MΩ min. at 100V DC | | **Dielectric Strength** | 250V AC for 1 minute | | **Contact Resistance** | 100mΩ max. | | **Operating Temperature** | -25°C to +70°C | --- ### 2. Physical and Mechanical Attributes The internal construction involves a metal dome contact that provides the "click" feedback to the user. * **Actuation Force:** Usually ranges between **160gf to 260gf** (grams-force). * **Travel Distance:** Roughly **0.25mm**, providing a short, crisp tactile response. * **Terminal Type:** Typically 4-pin configuration. Though it is a single-pole single-throw (SPST) switch, the 4 pins provide mechanical stability on the PCB; pins are often internally connected in pairs. --- ### 3. Circuit Representation In an electronic schematic, the TCS-41-R is represented as a simple open switch. Below is a conceptual representation of the pinout. ```text Pin 1 ---[ ]--- Pin 3 | Pin 2 ---[ ]--- Pin 4 (Pins 1 & 2 are usually tied together internally, as are Pins 3 & 4) ``` --- ### 4. Common Applications Due to its small footprint and reliability, the TCS-41-R is found in: 1. **Consumer Electronics:** Remote controls, microwave panels, and calculators. 2. **Input Devices:** Reset buttons on routers or mode-selection buttons on DIY electronics (Arduino/Raspberry Pi projects). 3. **Industrial:** Control panels where space is limited. ---
