why conductors of low tensile strength
1)produce greater sag and
2)can not be used for larger spans

In DC generator, we use commutator, having no. of segments. Then how it is possible to get a half wave of voltage and current for half rotation of armature?
I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
