[0002] A switch is an important signaling device used to reliably change the position of a turnout, change the direction of turnout opening, lock the turnout point, and indicate the position of the turnout. It effectively ensures driving safety, improves transportation efficiency, and reduces the workload of train operators. With the rapid development of my country's railway construction and the continuous increase in train speeds, switch machines play a key role in line guidance and ensuring operational safety.

[0003] Currently, most electric hydraulic switches are installed using bolts and nuts, which is cumbersome and time-consuming. Furthermore, switches need to be exposed to the air for extended periods of time. After prolonged exposure to wind and rain, the bolts and nuts on the switches are prone to rust, making it more difficult for technicians to disassemble the switches. Furthermore, the push-pull rods on the switches lack protective components, which can easily cause them to rust, affecting their flexibility. Rainwater can also easily seep into the switch housing through the gap between the push-pull rods and the switch body, causing the switch to malfunction and making it inconvenient to use. Currently, there is a lack of a new, reliable and durable switch that facilitates assembly and disassembly and protects the push-pull rods.
