Description and Introduction

0.300-INCH SEVEN SEGMENT DISPLAYS **Manufacturer:** QTC  

**Part Number:** MAN3940A  

**Specifications:**  
- **Type:** Tactile Switch  
- **Actuation Force:** 3.5g to 350g (adjustable based on compression)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Resistance Range:** >10MΩ (uncompressed), <1Ω (fully compressed)  
- **Lifecycle:** >1 million compressions
