Latching Relay Schematic. A latching relay is a subtype of electromechanical or electromagnetic switch commonly chosen in scenarios where the operator needs to control either switch off or amplify a large amount of current flow. Relay latching circuit using push button we connect relay and push button as per figure.
The wa4 mechanical latching unit for af tactors can be easily converted into compact latched contactors. The two schematic wiring diagrams below show how to wire an electrically latching relay circuit. This creates a basic memory function.
Relays are typically used when small continuous electrical currents must be used.
The latching relay has a small metal strip which can pivot between two terminals. To stop just press the button connected to relay 2 and the load will turn off and stay off until you push the 1st button again. The two schematic wiring diagrams below show how to wire an electrically latching relay circuit. The relay remembers which switch was pressed last.
