Description: BC-9 T top plunger limit switches are available in three designs. The first with an adjustable top push button which has a hex bolt and lock nut, the length of which can be adjusted up to 8 mm (adjustment is accomplished by locking the 8 mm spanner in the spindle and then turning the threaded 4 mm hex head operating plunger and securing it with a locknut). The second type has a solid button of 9.5 mm without any adjustment. The third type has a nylon roller of 17 mm diameter and 4.7 mm thickness. The top push operating heads are easier to apply because the operating direction and repeat accuracy is less critical.
