| switching element the output variable of which reproduces a change in the input variable from 0 to 1 delayed by the time interval of duration t1 and a change from 1 to 0 delayed by the time interval of duration t2 Note 1 to entry: The term delay has here another meaning than for continuous transfer elements. Note 2 to entry: Depending on the application, either the switch-on delay time t1 or the switch-off delay time t2 or both may be used. Note 3 to entry: In many applications the output variable remains at the value 0 if the duration of the time interval t0 during which the input variable has the value 1 is shorter than the duration of the switch-on time interval t1. Note 4 to entry: This entry was numbered 351-29-19 in IEC 60050-351:2006.
