[0002] Currently, there are various types of electromagnetic switches in existing technology, including one-button electromagnetic switches, which are simple to operate and convenient to use, greatly improving ease of use and effectiveness. In electromagnetic switches, the wiring structure generally uses wires wrapped around screws and then fastened to the terminals with screws. This method is prone to wire slippage and causes significant damage to the wire ends, affecting the service life.

[0003] To address the aforementioned issues, existing technology CN216528475U provides a one-button electromagnetic switch, comprising an electromagnetic switch, a terminal block, and a connection structure. The lower end of the electromagnetic switch is fixedly connected to a terminal block, and the end of the terminal block is fixedly connected to a connection structure. The connection structure includes a connection groove at the end of the terminal block, within which a conductive head is connected. The lower end of the conductive head is integrally formed and connected to a terminal sleeve. A wire is fixedly connected to the end of the terminal sleeve. Several evenly distributed support springs are fixedly connected to the upper end of the connection groove, and a push plate is fixedly connected to the lower end of each support spring. Both ends of the push plate contact the sidewalls of the connection groove. The space at the lower end of the connection groove forms a clamping groove, into which the conductive head is inserted. The advantages are: the convenient installation and disassembly wiring structure allows for easy disassembly of the wire connection; installation can be performed manually without tools, increasing operational convenience; and the connection stability is enhanced, preventing poor wire contact and slippage that could affect performance. Furthermore, it provides protection, reducing damage to the wire ends, extending their service life, and improving overall performance.
