CURRENT RELAY SWITCH
Current Sensing Switch, Normally Open Current Sensing Relay
1: Type: SZC is a current induction switch; 2: Model series: The maximum capacity of 23 series switches is 0@240V AC/DC; 3: NO stands for normally open, that is, when the through-core current is less than the set value, the switch is opened, and when the current is greater than the set value, the switch is closed;
Relay - Wikipedia
A relay is an electrically operated switch consists of a set of input terminals for a 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 make contacts, break contacts, or combinations thereof. Relays are used where it is necessary to control a circuit by an
Solid-state relay - Wikipedia
A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay, but as solid-state electronics contain no moving parts and have a longer operational lifetime. SSRs consist of a sensor which responds to an appropriate input
Relay Switch Circuit - Basic Electronics Tutorials
However a relay switch circuit can be used to control motors, heaters, lamps or AC circuits which themselves can draw a lot more electrical voltage, current and therefore power. The electro-mechanical relay is an output device (actuator) which come in a whole host of shapes, sizes and designs, and have many uses and applications in electronic
Transistors, Relays, and Controlling High-Current Loads
Sometimes you need to switch a high current circuit rapidly. In this case you would use a switching transistor. A transistor is an electronic device that can work as a switch. It allows control of a large current by a smaller current as does a relay. Unlike a relay, however, a transistor is not mechanical, and can operate much faster than a relay.

Current Rating: 30.0 amps , 40.0 amps : Maximum Switching Current: 30.0 amps : Measurement System: Imperial , Metric but wanted to wire fog lamps up in parallel to my headlights but didn't want the lights drawing power from my headlight switch, so I T'd the power of this relay off the headlight lead and now only the relay draws power from
Automotive Relay Diagram - Del City
12V DC relay switches are the best solution for full voltage applications, as they allow a low current flow circuit to control a high current flow circuit, like a vehicle's horn, headlights, auxiliary lamps, fan motors, blower motors and countless pieces of equipment existing on vehicles today. You can think of this as the switch in OFF
Bad Headlight Relay Symptoms and FAQ - In The Garage with CarParts
Aug 06, 2021A relay is basically an electromagnetic switch that uses low current to control a higher current circuit. Inside a relay, you’ll find a coil and a switching mechanism with a set of contacts. Most automotive relays are normally open, meaning current does not flow between the contacts until the relay is activated.
