HFD3/5-L1 – 5V 2A DPDT PCB Mount Relay – Hongfa Hongfa HFD3/5-L1 5VDC 2A DPDT Relay is an electrically operated switch. It consists of a set of input terminals for single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as making contacts, breaking contacts or combinations thereof. Relays are the most commonly used switching device in electronics. There are two important parameters of the relay, first is the Trigger Voltage, which is the voltage required to turn on the relay that is to change the contact from Common → NO. This product is known as 5V Hongfa Relay, 5V 2A Relay, 5V PCB Mount Relay, 5V DPDT Relay, DPDT 5V Hongfa Relay, DPDT 2A Relay, 5V Hongfa Relay.
