Panel mounting and construction information
The series 57M mounts easily into panels of minimum 0.5 mm and maximum 3 mm thickness. Front panel sealing to IP67 is
achieved by a sealing washer fitted to the body of the switch before it is inserted into the panel hole cut-out.
It is held onto the panel by means of a brass hex nut tightened down to a torque of 1-2 Newton Metre to achieve the correct
sealing pressure
