Relays & Switches

Relays are electrically operated switches that control the flow of current in electronic circuits. They allow a low-power control signal to switch a higher-power circuit, enabling control over devices requiring more voltage or current than the control system can provide directly. Common types of relays include:

• Electromechanical Relays: Use a moving armature to open or close contacts.
• Solid-State Relays: Utilize semiconductor components to switch circuits without moving parts.
• Reed Relays: Feature reed switches enclosed in a coil for rapid switching.
• Time-Delay Relays: Offer delayed switching actions for timing control.

Switches are fundamental electrical components that manually or automatically open and close circuits, controlling the flow of electricity. They come in various forms:

• Toggle Switches: Operated by a lever that moves up and down.
• Push-Button Switches: Activated by pressing a button.
• Rotary Switches: Controlled by rotating a knob to select different circuits.
• Slide Switches: Operated by sliding a button to open or close a circuit.
