Describe the subminiature micro switch.
What will be an ideal response?
The subminiature micro switch employs a similar spring contact arrangement as the basic micro switch. The subminiature switches are approximately one-half to one-quarter the size of the basic switch, depending on the model. Due to their reduced size, the contact ratings of subminiature switches range from about 1 ampere to about 7 amperes depending on the switch type.

Answer the following statement(s) true (T) or false (F)
1. Since parallelism (the perfect condition) cannot be produced, it is necessary to specify some allowance for parallelism deviation. 2. Since parallelism is an orientation tolerance, it controls the location of the toleranced feature. 3. A parallelism tolerance may be applied to a planar surface or a feature of size. 4. Location tolerances, such as position and profile of a surface, cannot limit parallelism deviation. 5. Where parallelism is applied to a diameter at MMC, the tolerance zone is a virtual condition boundary.
