The following switches are hand operated, control circuit devices, rated ‘Standard Duty.’ All of the switches have either one normally open or one normally closed (see chart below), slow make - slow break, Momentary contact. The mechanical life of these units is in excess of 500,000 operations. The small body (0.94" dia.) switches can be found as triggering devices on portable welding equipment. The larger units with cord grips have been used as circuit start switches wired to the end of a piece of SJO cable affording the operator greater flexibility in movement and vision. Their rugged construction and long term reliability make these switches extremely well suited to function within various environments.
