Slide switches are essential components in various electronic devices, offering a reliable and user-friendly method for controlling electrical circuits. This article provides a comprehensive overview of the slide switch, covering its basic structure, working principle, and performance specifications. It also highlights key features such as rated power, operating temperature range, and mechanical and electrical performance standards.
**Rated Power:** DC 50V, 0.3A
**Operating Temperature Range:** -20°C to 60°C
### **Performance Specifications of Slide Switches** Slide switches are tested under strict conditions to ensure they meet high-quality standards. Here are the main performance tests: 1. **Electrical Performance** - **Contact Resistance Test:** Conducted at 100 mA, the resistance must be below 30 milliohms. - **Insulation Resistance Test:** Apply 500V DC for 1 minute. The resistance between contacts and between the body and terminals should exceed 100 megohms. - **Withstand Voltage Test:** Apply 500V AC (50-60Hz) for 1 minute with a sensitivity current of 0.5mA. No insulation damage is allowed. 2. **Mechanical Performance** - **Operating Force:** Typically around 250 ± 50 gf. - **Terminal Strength Test:** Apply 500gf in any direction for 1 minute. No cracks or looseness should occur. 3. **Environmental Testing Conditions** - **Temperature:** 5°C to 35°C - **Humidity:** 45% to 85% - **Air Pressure:** 80kPa to 106kPa 4. **Durability Tests** - **Solderability Test:** Immerse the terminal in a solder bath at 230 ± 5°C for 3 ± 0.5 seconds. The welding area should cover more than 80%. - **Life Test (No Load):** Perform 100,000 cycles at 60 cycles per minute. Contact resistance must not exceed 200mΩ. - **Heat Resistance Test:** Expose to 85 ± 2°C for 96 hours, then cool to room temperature. No deformation or functional issues. - **Cold and Humidity Tests:** Place samples at 40 ± 2°C with 90–96% humidity for 96 hours, then test under normal conditions. ### **Components and Manufacturing Process** Slide switches are assembled from several key parts, each processed using specific techniques: 1. **Iron Shell:** Made from iron, often coated with nickel plating or blackening to prevent rust. 2. **Plastic Handle:** Usually made from POM or PA nylon for fire resistance and heat tolerance. Produced via injection molding. 3. **Terminals:** Crafted from phosphor bronze, typically electroplated with silver for better conductivity. 4. **Insulation Bottom Plate:** Made from electric wood board, stamped into shape. 5. **Contact Chip:** Phosphor bronze with silver plating for durability. 6. **Round Wave Beads:** Stainless steel, electroplated with nickel. 7. **Slingshot:** Made from bronze, formed by stamping. 8. **Decorative Oil:** Applied to the contact areas, available in red or green, non-toxic and eco-friendly. ### **Application Areas** Slide switches are widely used in many industries, including: - Audio and video devices (MP3, MP4 players) - Digital products (digital cameras, camcorders) - Communication equipment (mobile phones, PDAs, telephones) - Security systems (video intercoms, monitors) - Electronic toys - Computer peripherals (webcams, etc.) - Fitness equipment (body fat scales, treadmills) - Medical devices (blood pressure monitors, thermometers) Whether you're looking for high-quality slide switches for your project or want to learn more about their technical details, Kesta Switch Factory offers reliable solutions tailored to your needs.
