3 Dial Combination Lock Wiring diagram Schematic
3 Dial Combination Lock Circuit Diagram. Simply dial in the correct combination on the three rotary or thumb wheel switches. With the correct combination entered, current flows through Rl into Qls gate terminal, causing the SCR to latch in a conductive state. This sends a current through relay Kl, which responds by closing its contacts and actuating whatever load is attached.

After opening the lock, twirl the dials of SI through S3 away from the correct combination so that nobody gets a look at it. The lock will remain open and your load will remain on because the SCR is latched on. To lock things up, its only necessary to interrupt the flow of anode current through the SCR by pressing push button S4.
