CcacHe Electromagnetic Relay electromagnetic Effect Demonstration Normally Open Normally Closed Circuit Physics Teaching Instrument Experimental Equipment

Features

• Purpose: For middle school physics teaching to understand and study the basic structure and working principle of electromagnetic relays.
• Structure: This product is mainly composed of two parts: electromagnetic system and contact system. The electromagnetic system includes: electromagnetic coil, iron core armature; the contact system includes: a pair of normally open and normally closed contacts.
• Principle: The coil is energized, the iron core generates magnetism, the armature is sucked down, the coil power is disconnected, the iron core loses magnetism, and the armature resets, thereby controlling the controlled circuit.
• How to use: It is equipped with 9V DC power supply, and it can also be equipped with other controlled instruments (such as indicator lights, demonstration motors, etc.) for demonstration.
• Service:We attach great importance to customer experience, so you can contact us if you have any questions, and we will get back to you within 24 hours!
