A relay is a special type of relay that uses the properties of a PTC thermistor to control a circuit.
Contacts: There are contacts inside the relay, which are used to switch the on and off state of the circuit when the PTC thermistor reaches a certain temperature. The contacts are usually made of copper or other conductive metals.
Pins: There are metal pins on the bottom of the relay for connecting the power supply and control circuit. The design of the pins allows the relay to switch the on and off state of the circuit when it receives a signal.
Rated voltage: The relay is marked with "220V", which may mean that its rated voltage is 220 volts and is suitable for 220V circuit systems.
Model identification: The relay may be marked with a model or specification, such as "KSPAT4241379", which helps to identify the specific characteristics and application range of the relay.
Application: PTC relays are widely used in fields such as overcurrent protection, temperature control, and circuit protection. They can be used in household appliances, industrial equipment, automotive electronic systems, etc.
Brand: The relay is marked with "TRENDZ", which may be the brand name of the manufacturer.
Mounting: PTC relays are usually mounted on circuit boards by soldering or plug-in connections in a manner consistent with the manufacturer's instructions.
