XQ-5904 Microcomputer Switch Button Life Test Machine 
I. Brief Description of the Switch Button Testing Machine; 
This machine is suitable for testing the lifespan of switch buttons, such as wall switches, boat-shaped switches, lever switches, touch switches and flat switches, etc. Different test fixtures can be selected according to the customer's samples to meet the testing requirements. This machine is controlled by a microcomputer and uses text key input. It has adjustable speed, set number of tests, monitoring of conduction, and can conduct experiments in 2 or 4 workstations. The data will be retained after reaching the set number of tests. This ensures the measurement accuracy. 
II. Main parameters of the switch key testing machine; 
1.Power supply voltage: 220V ± 10% 50Hz 
2. Total count range: 0 - 99999999 (can be set arbitrarily) 
3. Travel range of the lower moving rod: As per customer's specification 
4. Height adjustment range for raising the pole: As per customer's specification 
5. Speed adjustment range: 5 - 60 times per minute (adjustable) 
6. Machine weight (approximate): 68 kg 
8. Test station: 2 groups or 4 groups (as specified by the customer) 
9. Each workstation conducts independent counting. If a product is damaged during the test, it will not affect other workstations. Other workstations will continue to operate until the total number reaches a certain limit or all products are damaged and the machine stops. 
10. Machine dimensions: Approximately 700*480*700mm 
11. Motor power: 90W 
12. Conductive wires: 2 sets or 4 sets 
13. Weighing weights: A set consists of 100g, 200g, 300g and 500g. Alternatively, you can purchase additional weighing weights as per your requirements. 
III. Operating Procedures for Switching Key Test Machine; 
1. First, fix the product onto the testing fixture. 
2. After fixing the product. 
3. The machine is powered on, the required test values are set, and the machine then conducts the test. 
4. Once the test value is reached, the machine will automatically stop, and the test result will be displayed clearly. 
IV. Precautions for the Switching Key Test Machine; 
1.Before conducting the test, please make sure that the power supply is properly plugged in or connected. 
2. Before conducting the test, make sure that the product is properly installed and fixed. 
3. The mechanical transmission parts must be maintained regularly. 
4. After the test is completed, it is necessary to ensure that the power supply has been turned off. 
5. It is strictly prohibited to use auxiliary corrosive liquids to clean the machine. Instead, rust preventive oil must be used. 
6. This testing machine must be used exclusively by one person. During the testing process, it is strictly prohibited to strike the machine or have anyone stand near it. 
7. The machinery must be grounded.
