Hongfa HF158F-12-ZS3T 12VDC 20A SPDT Miniature High Power Relay Hongfa HF158F-12-ZS3T 12VDC 20A SPDT PCB Mount Miniature High Power Relay A 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, break 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, this is the voltage required to turn on the relay that is to change the contact from Common → NC to Common → NO. Miniature high power relay offers low height, 20A switching capability, 5kV dielectric strength (between coil and contacts), and environmentally friendly product (RoHS Compliant) and meets IEC60335-1 reinforce insulation. This product is known as 12V Hongfa Relay, Hongfa Relay, 12V Miniature high power relay, 12V SPDT Relay, 12V SPST Hongfa Relay, Hongfa 12V 16A DC HF158F/12-H3T 6-Pin SPST Power Relay.
