[0002] In vehicle design, switch position adjustment is very important for improving vehicle performance and user experience. There are many switches on a car, and vehicle switches are an important part of the vehicle electrical system. They control various functions of the vehicle, such as lights, wipers, windows, doors, seat adjustment, entertainment systems, air conditioning, safety systems, etc. After the switches are produced, they usually need to be tested for durability.

[0003] In the process of testing the durability of a switch, the switch is usually fixed by a spring, and then a pressure sensor is moved by a moving mechanism to simulate the process of pressing the switch. The pressure is detected by the pressure sensor to facilitate the testing of the switch. However, in the process of fixing the switch by the spring, the position of the spring is usually fixed and the elastic force of the spring is constant. When it is necessary to clamp switches with a large size difference, the clamping force may be too large or too small, affecting the spring's ability to clamp the switch. Utility Model Content
