Sargent and Greenleaf S&G 6120 safe lock disassembly & troubleshooting Sargent and Greenleaf 6120 electronic safe lock disassembly and troubleshooting. Please post any questions and especially answers!! Thanks!! Electronic bination Lock | Detailed Circuit Diagram ... This 7 digit electronic combination lock can be easily hard wired for any combination that you choose. The circuit uses a 4 bit, divide by 8 Johnson counter (IC1), ten push button switches and NPN transistor T1. Simple Electronic bination Lock – Circuit Wiring Diagrams This could be the circuit diagram of a easy electronic combination lock by using IC LS 7220.This circuit may be applied to activate a relay for controlling (on & off) any device each time a preset combination of 4 digits are pressed.The circuit may be operated from 5V to 12V. bination lock A combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or cams , by using a set of several rotating discs with inscribed symbols which directly interact with the locking mechanism, or through an electronic or mechanical keypad.
