Abstract

The invention relates to a single-pole embedded type electromagnetic switch. The single-pole embedded type electromagnetic switch comprises an intelligent control module and a shell, an electromagnetic system is mounted under the intelligent control module, a contact system is mounted under the electromagnetic system, the shell is composed of a front shell and a rear shell, each of the front shell and the rear shell is correspondingly formed with positioning grooves for fixing the intelligent control module, the electromagnetic system and the contact system, and the front shell and the rear shell are assembled directly through slots. By means of the embedded type structure, the production technique is greatly simplified, and the reliability and the action consistency of the switch products are improved.

Description

technical field [0001] The invention relates to the field of electromagnetic switches, in particular to a single-pole embedded electromagnetic switch. Background technique [0002] Electromagnetic switch is a kind of control switch widely used, such as electromagnetic AC and DC contactors with large quantity and wide range, various control relays, etc. With the rapid development of smart grid and the continuous improvement of system automation, the requirements for switches are getting higher and higher. The reliability, consistency and long life of electromagnetic switches have been widely valued. At the same time, the introduction of intelligent control technology into low-voltage electrical appliances also puts forward new requirements for the main body of switching electrical appliances. Good control technology and control strategy require exquisite switching electrical appliances to cooperate with them. [0003] Since the electromagnetic switch is a frequently operated...
