Stepping Switch - The stepping switch is a spring-driven mechanism that rotates a series of cams that actuate contacts affixed to cantilever springs. There are a total of 36 steps in one complete revolution and the total time is a function of the timer. Therefore, to find the total time one has to multiply the step time by
36. Example: Step time is set for 0.5 seconds, giving a total time of 18 seconds
for one complete revolution.
