In exceptional cases, when the voltage has to be constantly switched on and off for a moment in relation to the on-time, instead of the contact (Normally Open) can be connected to the terminal (Normally Closed), thereby obtaining a reverse control (with switched output voltage control and administration of the relay coil, the voltage across the contact (Normally Closed) disappears) .
Katika kesi ya kipekee, wakati voltage ina kuwa daima kimewashwa na mbali kwa muda katika uhusiano na juu ya – wakati, badala ya kuwasiliana (Kawaida Open) yanaweza kushikamana na terminal (Kawaida Ilifungwa), hivyo kupata udhibiti reverse (na switched pato voltage udhibiti na utawala wa coil relay, voltage hela wasiliana (Kawaida Ilifungwa) kutoweka) .
