The **KURE-43M2-R** is a specific electronic component, typically classified as a **Tactile Switch** (also known as a micro-switch or momentary push-button). These are widely used in consumer electronics, automotive interfaces, and industrial controls.
Below is a detailed breakdown of its specifications and characteristics.
---
### 1. General Specifications
Tactile switches like the KURE series are designed for low-current applications where physical "click" feedback (tactile response) is required.
| Parameter | Typical Value |
| :--- | :--- |
| **Type** | Momentary Tactile Switch |
| **Mounting Type** | Surface Mount (SMD / SMT) |
| **Circuit** | SPST - NO (Single Pole Single Throw - Normally Open) |
| **Operating Force** | 1.6N to 2.5N (varies by specific sub-model) |
| **Travel** | ~0.25mm |
| **Rated Voltage/Current** | 12V DC / 50mA |
| **Contact Resistance** | < 100mΩ |

### 2. Physical Construction
The KURE-43M2-R is engineered for durability and compact sizing. Its construction usually involves:
* **Actuator:** The top button part that the user presses.
* **Cover/Frame:** Typically made of stainless steel or high-temperature plastic to withstand reflow soldering.
* **Contact Dome:** A metal snap-dome (often stainless steel) that provides the "click" sound and completes the circuit.
* **Terminals:** Silver-plated or Gold-plated leads for Surface Mount Technology (SMT) integration.

### 3. Key Features
* **Tactile Feedback:** Provides a sharp, clear "click" sensation, confirming to the user that the button has been successfully pressed.
* **Low Profile:** The "43" in the series often refers to the specific height or footprint dimensions, making it suitable for thin devices like remote controls or smartphones.
* **High Reliability:** Designed for a high number of operating cycles (typically 100,000 to 500,000 cycles).
* **Environmental Sealing:** Depending on the exact revision, these often feature basic dust resistance.

### 4. Typical Applications
The KURE-43M2-R is commonly found in:
1. **Consumer Electronics:** TV remote buttons, camera shutters, and smart home hubs.
2. **Computing:** Reset buttons on motherboards or side buttons on mice/tablets.
3. **Automotive:** Steering wheel controls or dashboard interface buttons.
4. **Medical Devices:** Control panels for portable diagnostic equipment.
