[0002] The instrument switch is the main switch that controls the "on" and "off" of the instruments and instruments of underwater vehicles. Usually, the instruments and instruments of the vehicle are manually controlled outside the product. As the last insurance of the vehicle, the instrument switch is an important component to ensure the safety of the vehicle, the deployment platform and personnel. During the service process, some instruments and instruments need to be turned on at the last time before the vehicle enters the water. In order to avoid misoperation or malicious damage, the anti-misoperation and anti-malicious damage functions of the instrument switch are extremely high. At present, there are two main types of instrument switches for underwater vehicles. The first is the angle rotation switch mode, which switches the switch between the "on" and "off" states by rotating the shaft to a certain angle; the second is the travel switch mode, which switches the switch between the "on" and "off" states by driving the cam to move a certain distance through the shaft. In practical applications, the existing instrument switches for underwater vehicles have the following shortcomings: 1. Lack of reliable safety insurance measures; 2. The "on" and "off" positions are not accurately positioned and the markings are not obvious.
