About this product
A 5 V DC single-pole double-throw (SPDT) PCB relay with a fully sealed body. It lets a low-power control circuit switch higher-voltage or higher-current loads. The coil has about 270 Ω resistance and needs roughly 4.5 V to switch reliably, so it is usually driven from a 5 V logic output through a transistor.

Frequently asked questions
What is the price of T78L-DC5V-C 5V DC SPDT Fully Sealed PCB Relay in Egypt?
T78L-DC5V-C 5V DC SPDT Fully Sealed PCB Relay currently costs 30 EGP in Egypt.
Where can I buy T78L-DC5V-C 5V DC SPDT Fully Sealed PCB Relay in Egypt?

How do I drive this relay from an Arduino or ESP32?
The coil draws about 100 mA at 5 V (530 mW), more than a typical microcontroller pin can supply. Use an NPN transistor or MOSFET with a base or gate resistor, and place a flyback diode across the coil.
What do the SPDT contacts do?
COM is the common contact. NO (normally open) connects to COM when the coil is energized. NC (normally closed) connects to COM when the coil is de-energized. Check the contact rating for your load before wiring, as the listing quotes different current ratings.
