Addendum
What is the use of SK7 ?(I think)
SK6 is an unfit type of switch to interrupt the motorcurrent,it does its job in slow motion with sliding contacts resulting in a lot of sparking and contacterosion .Therefore the quick acting (microswitch like?)SK7 is parallel to SK6 taking over the actual interruption .In the short time it takes for SK7 to reach its open sector the contacts of SK6 are safely opened and in the correct position.
