Mounting Positions
Compression Models
The best mounting position for a tension model is on the dead end of the
line or on a crane anchor point. This mounting minimizes the effects of the
machinery’s motion on the Dynaswitch. It keeps the switch in one relative
position which reduces the possibility of wire tangling and connector
damage.
Position the Dynaswitch so that all of the supported load is transmitted
through the compression ball fitting. Bolt the bottom leg to the loading
machinery or the facility foundation. Make sure the load contacts the
Dynaswitch only at the top of the steel ball and nowhere else! If the load
rests on the upper leg as well as on the ball, the microswitches will not
actuate at the proper load setting. Do not restrict free motion of the upper
leg since this too could cause the Dynaswitch to activate improperly.
Some compression models
have flat-top balls; rest the
applied load on the flat
surface of the flat-top ball.
