Timer switch ZN

Area of Application

These switches are used whenever electrical components should be switched delayed in a certain and simple way. Typical applications are time delayed turnoffs of fans ventilating bath rooms or ovens to remove water condensation.


If control voltage is applied to the control leads, the working contact closes time delayed. This contact system is galvanic separated from the control leads. After removing control voltage the contact keeps closed for another delayed time which depends on surround temperature and the time control voltage was present.
