Weldability test parameters of toggle switch:
1. Weldability test
The top of the terminal is immersed in a tin soldering pool at a depth of 1 inch and the temperature is 230 (+5 C) for 3 (+0.5 seconds).
Be careful:
(1) Welding time should be less than 3 seconds
(2) The welding area should be more than 75%.
2. Welding resistance test
The temperature of welding furnace should be controlled at 260 5 C, the overheating time should be 3 0.5 seconds, and the temperature should be controlled at 320 5 C and 3 0.5 seconds when the thickness of substrate is 1.0_ by hand.
Requirements: Must satisfy the body without deformation, meet the mechanical and electrical energy.
3. Life Testing
No-load: The operator performs 100,000 no-load tests at 60 times per minute.
Requirement:
(1) Contact resistance should not exceed 200 m_
(2) Other, satisfied with mechanical and electrical performance.
4. Heat Resistance Test
After 96 hours of testing at 85 2 C, the test was conducted at normal room temperature for 1 hour.
Requirements: No abnormal appearance, meet the mechanical and electrical performance.
5. Cold Resistance Test
Place it at 40 2 C. After 96 hours in 90 - 96 degrees of relative humidity, the samples were put in normal environment for 1 hour for testing.
Requirements: No abnormal appearance, meet the mechanical and electrical performance.
6. Moisture test
Place it at 40 2 C. After 96 hours in 90 - 96 degrees of relative humidity, the samples were put in normal environment for 1 hour for testing.
Requirements: No abnormal appearance, meet the mechanical and electrical performance.
