Bistable flip-flop latch switch circuit module button trigger power-off memory^P:
$7

The main purpose is to prevent false triggering of the switch, and the other optional power memory function on again after power electrical output hold state before the power failure. Features: 1. Common Feature: falling edge. Suppose the initial state of the output terminal Vo is open, the trigger once, Vo output terminal goes high once again trigger, Vo output terminal becomes an open state, and so on. 2. Anti-false triggering function: the trigger signal must persist for some time to be effective, time can be freely set between 1s-7s (increments of 1 second). 3. Default electrical output after the initial state is open. Can also be set to power memory function on again after power electrical output hold state before the power failure. 4. Contains a switch contact inputs stabilization circuit, the action is very reliable. 5. Output with protective diode, can be directly connected relays and other inductive loads. Power supply voltage:DC 3V-18V. Quiescent Current: the closed state consumes only 2uA, work state power consumption of about 2mA. Output:1500mAcan directly drive a long time within the resistive load (short can withstand 2500mA current); Purpose: self-locking switch transformed into micro-switches, flashlight switch. Size: free pin size 14mm × 11mm. Pin pitch 2.54mm. Setting method: The back of the module has the following 4 set of pads were marked with numbered 1-4.
