Universal Switch Adjustable Time Capsule ®
Model No. 438USA-X Description:
The popularity of the original Model 438USA generated the requirements for
Universal Switch Adjustable models with both shorter and extended timing
ranges, along with special operating voltages. The model 438USA-X performs
exactly as the 438USA, but with both timing and voltage ranges specified. By
merely connecting the two terminals in series with any load circuit drawing
between ten milliamperes and one ampere operating from the specified
voltage range, the 438USA-X turns that load circuit into a delay on make timing
circuit. Set the 10 DIP switches to the required delay, and apply operating
voltage. “X” is replaced with a digit from 1 to 4
