Am finishing my rounter cabinet [been gathering parts/materials lets say, years] and want to know if there is a reason to use plastic instead of metal switch boxes, or vice-versa. Have metal but I read on a posting here that plastic should be used. The second means just another trip to the store [the last?] but another delay.
All that is left now is to install dust collector fittings and then switches on each end with the master on the back. Added the L/R end emergency switches with kneeable large flat on/off buttons, as several folks recommended in other posts. These are the modern flat wall switches that were the rage in the 50's or so, not the red and green ones normally seen with the large paddle stop. These will be in series with the master to permit any of the three switches to shut the motor off. Any one know a reason not to do it this way? I am a little concerned with having a switch box projecting into the cavity that contains the router/motor since the boxes are not dustproof, but otherwise ok.
So plastic or metal switch boxes, and other comments? Thanks for any help.
