LY101 overspeed switchDetailed product description：

LY101 overspeed switch is a new series of products developed by absorbing advanced foreign technology and combining it with domestic practical needs. The product has exquisite appearance, high switch action accuracy, forward and reverse bidirectional protection, high protection level, can withstand a wide range of environmental temperature changes, and is easy to install. This series of products features an automatic reset mechanism.

2. Product performance:
The product is widely used in industrial fields such as lifting, metallurgy, and ports, and is a speed control device that restricts rotating machinery, lifting and hoisting systems, and other devices that require safety protection. It is often combined with DC speed measuring generators and encoders to generate and control speed signals, making it an ideal and reliable protective device.
