Auxiliary Contact Blocks
Frequently it is necessary to have more auxiliary contacts operated by a single contactor. Additional contacts may be made available by the use of auxiliary contact blocks. These contact blocks are available with one, two or four contacts. From these it is possible to obtain any number of normally open and / or normally closed contacts from one to four.
Figure 32 shows an auxiliary contact block having four contacts. It has two N/O and two N/C
