A latching circuit is a circuit with two stable states, which one can think of as 1 and 0, thereby being able to store one bit of information. In circuit diagrams, these are represented by cross-coupled NOR or NAND logic gates.
Latching Current is the minimum current needed on the gate to fire or trigger an SCR.
The doorknob may not be latching properly due to misalignment, wear and tear, or a loose screw.
once the gate has triggered conduction between cathode and anode, the gate has no further control; conduction will continue until power is removed from the cathode to anode circuit.
we know that ratio of holding current to latching current in scr is 0.4.
The door handle may not be latching properly due to wear and tear, misalignment, or a faulty latch mechanism.
The door knob may not be latching properly due to misalignment, loose screws, or a worn-out latch mechanism.

The door may not be latching properly due to misalignment of the latch mechanism, a worn-out latch, or a problem with the door frame.
The door may not be latching properly due to misalignment of the latch mechanism, worn out latch components, or a loose door frame.
Latching current is the current flowing between anode to Cathode when thyristor is turned on using gate pulse. If the gate pulse is removed before the required min amount of latching current value is not reached thyristor will turn off. To keep the thyristor in on state the gate pulse duration should be so adjusted that the min latching current value is reached before it ends.
The door may have stopped latching properly due to wear and tear on the latch mechanism, misalignment of the door and frame, or a loose screw or hinge.
Your interior door may not be latching properly due to misalignment of the door and frame, loose screws or hinges, a damaged latch mechanism, or a warped door.
