adjusted in any position.
Microswitches are voltage-free.
The contact capacity is 5 A/250 Vac with ohmic load and 1 A/250 Vac with inductive
load.
Contact rating is about 5 A/250 with Ohm load and about 1 A/250 with inductive load.
For adjusting the cams of auxiliary microswitches, proceed as for cams of endswitches
as indicated in paragraph 9.1 chapter 9 “CALIBRATIONS”.
