Plug-In LED Red Top

Q: Does it need a resistor?

The resistor requirement should be confirmed from the final product design; an external resistor may be required if the module does not include one.

Product Code : SCL-EI-10625

The Plug-In LED Red Top from Lab Glassware Manufacturer, a scientific and educational equipment manufacturer based in Ambala, Haryana, India, since 1982, is a modular red light-emitting diode element used for school physics circuits, electronics demonstrations, and STEM training boards. It is supplied to schools, colleges, and institutional buyers across India and exported to countries including Greece, Italy, Portugal, and Malta as part of the company's Southern Europe science-education supply.

Quick answer: The Plug-In LED Red Top inserts into a compatible modular circuit board to give students a visible red light output when a circuit is connected correctly, making polarity, current flow, and open/closed circuit conditions easy to observe. It should be used with the correct current-limiting resistor and a properly rated low-voltage supply.

How to Use the Plug-In LED Red Top

Check the confirmed voltage and current rating before connecting the LED element.
Insert the plug-in LED into the compatible teaching board or circuit panel.
Connect the LED in the correct polarity as per the circuit diagram.
Use the required current-limiting resistor if it is not built into the module.
Apply the recommended low-voltage supply and observe the red light indication.
Disconnect the power supply before removing or changing the LED element.

Safety note: Use the Plug-In LED Red Top only with correctly rated low-voltage circuits. Do not connect the LED directly to mains electricity or to an unprotected power source.

Care & Maintenance

Store the LED element in a dry, labelled component box after use.
Keep plug-in contacts clean, dry, and free from dust or corrosion.
Do not exceed the confirmed current rating of the LED element.
Replace the unit if the LED does not glow, the top is cracked, or the connector is loose.

Building a Complete Plug-in Indicator Circuit

The Plug-In LED Red Top is designed to work with modular teaching boards. Combine it with the Plug-in Board for Building Components, control it with the Plug-in Element Lever Switch, and add the correct current-limiting protection with Resistors for Breadboard to build a complete, safe plug-in indicator circuit for classroom demonstrations.

Frequently Asked Questions

What is a Plug-In LED Red Top used for?
A Plug-In LED Red Top is used as a visible red indicator in school physics and electronics circuits. It helps students observe circuit completion, polarity, and current flow.

Is this LED suitable for school students?
Yes. It is suitable for supervised school and STEM experiments when used with the correct low-voltage supply and compatible plug-in circuit board.

Does the LED need correct polarity?
Yes. An LED is polarity-sensitive and should be connected according to the circuit diagram; if connected incorrectly, it may not glow.

Does it need a resistor?
The resistor requirement is confirmed on the final product design — see our Resistors for Breadboard if an external resistor is needed.

Can it be used with a lever switch or push-button switch?
Yes. It can be used with compatible switches to show how opening and closing a circuit controls the LED indicator.

What details should be confirmed before purchase?
Confirm voltage rating, current rating, connector style, compatible board type, resistor arrangement, quantity, and whether additional accessories are included.
