Rated power: DC 50V, 0.3A
Operating temperature range: -20°C to 60°C
Comprehensive performance of the toggle switch includes:
1. Electrical Performance Specifications:
- Contact Resistance Test: Conducted under a low current (100 mA).
Requirement: Must be less than 30 milliohms.
- Insulation Resistance Test: Apply 500V DC for 1 minute using the following contact method:
(1) Between contact terminals.
(2) Between the plastic body and the terminal.
Requirement: Must exceed 100 megohms.
- Withstand Voltage Test: Apply AC 500V (50-60Hz) for 1 minute with a sensitivity current of 0.5mA:
(1) Between the contacts and between the legs.
(2) Between the legs and the housing.
No insulation damage or anomalies allowed.
2. Mechanical Performance Specifications:
- Operating force: Typically 250 ± 50 gf.
- Terminal strength test: Apply 500gf in any direction for 1 minute.
No cracks or looseness in the terminal row is acceptable.
- Test conditions: Temperature 5°C–35°C, humidity 45%–85%, air pressure 80kPa–106kPa.
3. Durability Tests:
- Solderability Test: Immerse the terminal top in a solder bath at 230 ± 5°C for 3 ± 0.5 seconds.
Note: Welding time must be under 3 seconds, and the welding area should be over 80%.
- Additional solderability test: Use a reflow oven at 260 ± 5°C for 3 ± 0.5 seconds, with a substrate thickness of 1.0mm.
Hand-welding temperature: 320 ± 5°C for 3 ± 0.5 seconds.
Requirement: No deformation, and all mechanical and electrical properties must be satisfied.
- Life Test (No Load): Perform 100,000 cycles at 60 cycles per minute.
Requirements: Contact resistance must not exceed 200mΩ, and other properties must meet standards.
- Heat Resistance Test: Place at 85 ± 2°C for 96 hours, then return to room temperature for 1 hour.
Requirement: No visual defects, and all electrical and mechanical properties must remain intact.
- Cold Test: Expose to 40 ± 2°C and 90–96% humidity for 96 hours, then test after 1 hour at normal conditions.
Requirement: No visible damage, and all properties must be maintained.
- Humidity Test: Same as cold test conditions.
Requirement: No abnormal appearance, and all properties must be satisfied.
Toggle switches are composed of several components assembled through specific processes:
1. Iron shell (material: iron; treatment: electroplated nickel or blackened to prevent oxidation).
2. Plastic handle (material: POM; fire-resistant or high-temperature resistant options use PA nylon, processed by injection molding).
3. Terminal (material: phosphor bronze; treatment: electroplated silver).
4. Insulation base plate (material: electric wood board; process: stamping).
5. Contact chip (material: phosphor bronze; treatment: electroplated silver).
6. Spring washer (material: stainless steel; treatment: electroplated nickel).
7. Spring (material: bronze; process: stamping).
8. Decorative oil (non-toxic, eco-friendly chemical oil used on terminal and base plate surfaces for aesthetics).
Applications of toggle switches include:
1. Audio and video devices: MP3, MP4 players.
2. Digital products: digital cameras, camcorders.
3. Communication equipment: mobile phones, car phones, telephones, PDAs.
4. Security systems: intercoms, monitors.
5. Electronic toys.
6. Computer accessories: webcams, etc.
7. Fitness equipment: body fat scales, treadmills.
8. Medical devices: blood pressure monitors, thermometers, hospital call systems.
