This Latching Circuit is a circuit which locks its output when a momentarily input trigger signal is applied, and retains the same state even after the input signal is removed. This State will remain indefinitely until the power is reset or some external signal is applied. Latch circuit is similar like SCR (Silicon Controlled Rectifier) and can be very useful in various circuits like alarm circuits.
Here is a very simple latch circuit which can be used to trigger the AC mains loads and alarms.
