Top 3 Customer Questions & Concerns 🙋‍♂️

1. ⚡ What is the benefit of the TV-5 rating?

   • The TV-5 rating means this relay is specifically designed to handle the momentary "inrush" current that occurs when a device like a television or motor is first turned on, preventing the contacts from welding together.

2. 🔧 Can I use this relay for 5V microcontroller projects?

   • Since the coil requires 12V DC, you cannot trigger it directly from a 5V Arduino pin. You will need a transistor (like a 2N2222) to switch the 12V supply to the relay coil.

3. 💪 What is the default state of the relay?

   • This is an SPST-NO (Normally Open) relay. The circuit is disconnected until you apply 12V to the coil, at which point the contacts close to power your device.
