<p>The cyclic control switch for connecting and cutting an electric current includes a synchronous electric motor driving a cam mechanism. The cam is driven at a predetermined speed defining the length of the operating cycle. A microswitch having a rapid action is pivoted in the frame of the switch, with a control arm being operated by the cam to change the switch. An elastic element holds the body of the microswitch and the control arm against the cam. An adjustable stop acts on the body of the microswitch to determine the time of operation of the switch during each cycle.</p> |
