General Purpose Relay SPDT (1 Form C) 12VDC Coil 12A Through Hole 5 Pin
The General Purpose Relay SPDT (1 Form C) with a 12VDC coil and 12A switching capacity is a compact, reliable solution for switching applications in automation, control systems, and electronic projects. Featuring a Single Pole Double Throw (SPDT) configuration, also known as 1 Form C, it offers both normally open (NO) and normally closed (NC) contacts, making it suitable for flexible control scenarios.
This relay can handle up to 12A at 250VAC or 30VDC, enabling it to switch moderate power loads like motors, lamps, and other electrical devices. Its through-hole design with 5 pins allows easy integration into PCBs, breadboards, or custom electronic circuits.
Ideal for use in home automation, industrial control, power management, and DIY electronics, the relay provides galvanic isolation between the control circuit and the load, improving system safety and stability.
Its 12VDC coil voltage makes it compatible with most microcontroller platforms (such as Arduino, Raspberry Pi, and PLCs), requiring only a small control current to activate. The relay’s durable build ensures long life and consistent performance, making it a trusted component in a wide range of general-purpose applications.

Relay Pin Configuration:
| Pin Number | Pin Name | Description |
| 1 | Coil End 1 | Used to trigger(On/Off) the Relay, Normally one end is connected to 12V and the other end to ground |
| 2 | Coil End 2 | Used to trigger(On/Off) the Relay, Normally one end is connected to 12V and the other end to ground |
| 3 | Common (COM) | Common is connected to one End of the Load that is to be controlled |
| 4 | Normally Close (NC) | The other end of the load is either connected to NO or NC. If connected to NC the load remains connected before trigger |
| 5 | Normally Open (NO) | The other end of the load is either connected to NO or NC. If connected to NO the load remains disconnected before trigger |
