Multi Control (CB4383E)

Details
Written by: Newton C. Braga

 

This circuit was obtained from a 1965 magazine, but can still be assembled if we use a modern 6 V x 100 mA relay and a BD135 transistor. The other components can still be obtained on the market. Among the jacks can be connected sensors of various types.
