What is Single Pole Single Throw Relay
SPST relay is an ordinary and very common electric switch used to control the current on or off. It is composed of a switch contact-single pole single throw, which can only change between "open" and "closed" states in different circuits. In simple words, SPST relay is similar to a remote control switch able to control current flow based on the principle of electromagnetic induction. Normally, these relays are widely used in the field of automation control system, household appliances, industrial equipment, etc.

The working principle of SPST relay
- The working principle of SPST relay is very simple: when current passes through the coil of the relay, the coil generates a magnetic field, which pulls the internal contact switch. This switch can connect or disconnect circuits and control the flow of current. Once the power is disconnected, the contacts will return to their original position and the circuit will be closed.
- Switch type: The SPST relay has only two contacts: normally open (NO) and normally closed (NC).
- Working principle: When the coil current of the relay passes through, the normally open contacts close, allowing current to flow; When the current stops, the contacts open and the current is interrupted.
