JZ-4 Type Anti High Frequency Electromagnetic Wave Interference Medium Power RelayDetailed product description：

1、 Purpose:
JZ-4 type is a lock key electromagnetic relay that can work normally in high-frequency electromagnetic wave environments without misoperation. Used for signal indication and protection in power network equipment, high-frequency equipment, electromagnetic interference equipment, automatic control or communication equipment.
The characteristics of this relay are its sturdy structure, strong vibration resistance, and dual-use of AC and DC. The contact system has four sets of contacts (3-4, 5-6, 7-8, 9-10). When the button is pressed, the teeth on the armature lock the disc on the moving contact shaft, causing contacts 3-4, 7-8 to close and contacts 5-6, 9-10 to open. When the relay armature is engaged, the source disk disengages and the moving contact shaft quickly resets, causing contacts 5-6, 9-10 to close and contacts 3-4, 7-8 to open. If you want to reuse it, you must press the button again so that it can repeat the above actions.
