Manual switches, which consist of consecutive order of more than one same contact slots on a shaft and which can rotate around an axis ; which are used in motor connction works, measurement device commutators and control and distribution panels, are called Cam (paco) switches. Medium and large-power motors are controlled with contactors and relays. However, as controlling of small-power motors are more economical and simple, they are controlled with Cam switches. Federal Cam switches are manufactured in accordance with IED60947-3 / EN 60947-3 and CE. Cam switches, which have two, three or four silver-alloy contacts in each slice, are utilized in various controlling operations by increasing number of slices. Moving contact has a swaged surface, whereas fixed contact has a flat one. In this way, full contact and lowest resistance are ensured. Since contacts are opened and closed by pressing and cams on the shaft perform simultaneous opening-closing of contacts, it has been allowed to open and close all the controlling circuits or phases at the same time without any delay.
