Electrical connections and multimotor mechanisms

[kmcclary]

Does the "no switches" basically apply to commercial switches?

Complex mechanisms often have safety or sequencing "devices" to allow for proper positioning.
Can we use allowable materials to create something that will make, break or change simple electrical connections based on physical position of one mechanism section (such as an end of travel condition) to enable or disable a second motor on a single Spike channel? This allows for motor "motion sequencing" in a complex mechanism by pushing one button, or attaining a proper actuator position even if operator visibility is blocked.

For example, can we use two pieces of copper pipe coming in contact with each other (or separating) to start or stop a second motor attached to the same Spike channel once a certain position is reached, or to disable it so it won't try to move something else for mechanism safety? In essence,
may we homebrew connections of ANY kind?

Thanks!
