An electromagnetic switch operates using an electromagnet to control the opening and closing of electrical contacts.
- Operation: When current flows through the coil, a magnetic field is generated, pulling the armature to close or open the contacts.
- Common Types: Relays, contactors, solenoid valves.
- Applications: Industrial controls, automotive systems, power distribution.
- Key Components: Coil, core, armature, spring, contacts.
Note: Ensure proper voltage rating and contact load compatibility when selecting a switch.
