* If you use three Contact Blocks in stage 1, you can add one more Contact Block in the middle of stage 2.
Note: If you increase the number of Contact Blocks, evaluate the Switch under actual working conditions before permanent installation and use
the Switch within a number of switching operations that will not adversely affect the Switch’s performance.
