Timing of instruction is a critical aspect of teaching. 20 minute periods of instruction are adequate for students in a insructional course that is mostly hands on.
Allen,
Sounds like this is a great way to promote critical thinking among your students. This is great, and readies students for what they will encounter in the workforce.

After I finish a section of the lecture I pass around components of the lecture and ask them to test them with their equipment.
I then ask for them to go to the lab and look up the specifications and check the results.
Some students say,this is too easy, what do I learn from this.
I then ask, give me a list of reasons that these components can be damaged and how can it occur.
What caused the problem.
You will be given credit only for correct diagnosis.
Steven,
Right. Sometimes it seems like 20-25 minutes is not long enough to cover everything prior to a break or change up. But these don't have to be long, just doing something a little different, an alternate activity, a nother way to engage students (like involving them in the instruction), these are all ways to keep attention and focus on topic.
