Due to this method of mounting, the metal switches can be used in applications with limited assembly space or where the access to the rear side of the housing is not possible. This means that the switches can adapt where conventional switches will not be applied. Furthermore, this type of mounting realizes cost savings by a significant reduction of assembly time. The assembly becomes effective by the force fitting of the switch into the drilling hole, whereas the O- Ring will be displaced. After inserting the switch through the drilling hole, the O-Ring expands and the switch is fixed in the drilling hole. It must be pointed out that the panel cut-out is without flash and the set-up of the drilling diameter has to lie in a minimum range of tolerance (+ 0.15 mm to the nominal drilling diameter), so that a protective position of the switch can be guaranteed. Also the thickness of the front panel is important as the position of the switch is determined by the panel thickness. By using sharp objects the switch can be released from the front panel. Therefore, switches with such an assembling technique are only suitable to a minimum extent in applications which are exposed to vandalism. 2 DATA AND DIMENSIONAL DRAWINGS 2.1 Technical Data The technical data for the assembling of the snap-in switches is listed in this section. The mechanical, electrical and climatical features of the used switches are described in their particular product manuals. Mounting Diameter [mm] 19, 22, 24, 27, 30 Standard Front Panel Thickness [mm] 1.5; 2.0; 2.5; 3.0 Assembly Force [N] 50 - 100 Drilling Tolerance [mm] max. + 0.15 Panel cut-out without flash Torsion Protection without Torsion Protection If the switch is assembled in right direction, lettered switches can be used. ESD-Protection In combination with a coated or anodised surface of the front panel the ESD protection cannot be guaranteed. |
