13. ame point in each cycle of machine operation The point in the machine cycle that the switch is turned ON is commonly known as the TIMING whereas the length of time that the switch 15 ON is termed the DWELL TIMING and DWELL can be provided by mounting a mechanical cam on a rotating shaft such that it can make contact with a corresponding electrical switch The portion of the cam that comes in actual contact with the switch is often known as the LOBE The design of the cam must allow the user to be able to set both the TIMING and DWELL of the LOBE Several cam switch assemblies can be placed on the same shaft to provide independent TIMING and DWELL for a number of different machine functions Each cam switch assembly is commonly known as a CIRCUIT Mechanical cam switches can be very time consuming to set when more than a few circuits are required In addition mechanical cam switches are not practical in applications where the switch must be turned ON and OFF a number of times during a single machine cycle CMULTIPLE LOBES A programmable limit switch is a device which overcomes the shortcomings of mechanical cam switches by performing the cam functions electronically rather than mechanically Instead of having to physically adjust the TIMING and DWELL of a number of mechanical cams the programmable limit switch PLS allows a user to enter the TIMING and DWELL settings via a keyboard The TIMING and DWELL settings ar
