About This

• WORKING PRINCIPLE: When the coil is energized, the iron core generates magnetism, absorbs the armature, when disconnects the power supply, the iron core loses magnetism, causing the armature to reset, thereby controlling the circuit.
• VERSATILE USAGE: This instrument can be used with a 9V DC power supply, can also be paired with other controlled instruments such as indicator lights or demonstration motors for circuit demonstrations.
• PREMIUM CONSTRUCTION: Made from premium materials, this instrument is to , ensuring durability. Compact and lightweight, convenient to use.
• HIGH PERFORMANCE: Professionally manufactured, this experimental equipment has stable characteristics and high reliability, providing consistent and
• WIDE APPLICATIONS: This demonstration electromagnetic relay equipment finds extensive application in kids science projects, physics or mechanical learning, classroom teaching demonstrations, etc.
