Abstract: A control mechanism for use on an open-end spinning machine provided with a sensor which senses tension in yarn being produced and a switching mechanism for interrupting a fiber feed device responsive to the sensor sensing a drop in yarn tension. The switching mechanism includes a switch-on member 3 and a main switch member 4 that is switched on upon actuation of the switch-on member for putting the sensor 10 and fiber feed device out of service. A switch-off member 5 is provided for switching off the main switch member 4 for putting the sensor and the fiber feed device 60 back into service.

Abstract: A housing for holding a thread monitor of an openend spinning machine including a first attachment which secures a switching member to a cover and a second attachment for aligning the housing relative to the support cover. The support cover has recesses provided therein through which the first and second attachments extend for securing and aligning the housing relative to the support cover.

Abstract: A housing for holding a control device for a thread monitor of an open-end spinning machine which includes heat-generating elements. The housing is primarily constructed of plastic material and includes a cooling plate upon which the heat generating elements are mounted for dissipating heat generated within the housing.
