4.2.2 Definitions
SWITCH
A device of the electrical installation with an operating element that is actuated by pressing,
turning or tilting. The electrical contact is closed by any actuation and remains in this state until
the operating element is actuated again.
An example for this is the actuation of a light switch. If this is pressed, the living room lamp
switches on and lights continuously. If the light switch is actuated a second time, the living room
lamp switches off again.
BUTTON
A device of the electrical installation that is actuated by pressing and then returns to the starting
position. The electrical contact is only closed for the duration of the actuation.
An example for this is the actuation of a bell button. The doorbell can be heard while the bell
button is kept pressed. As soon as the bell button is released, the doorbell can also no longer be
heard.
DELAY TIME
The 1-channel relay and electronic 1-channel switch inserts operate as switches. This means they
switch on the lighting for the first actuation and off again for the subsequent actuation. A delay
time can optionally be set for the 1-channel relay switch insert. After expiry of the delay time, the
switch insert switches off the lighting again automatically. The load can also be switched off
manually using the centre plate during this delay time.
Proceed as follows to set the delay times of the 1-channel relay switch insert:
− Switch (no delay time)
− 1 minute
− 5 minutes
− 30 minutes
− 60 minutes
The delay time function is primarily an energy saving function: Particularly for rooms in which no-
body is continuously present (for example office kitchens), the light is switched off automatically
after a specific time. However, the function can also be used so that, for example when leaving
the house, the light in the hallway continues to light to give the impression that there is still a per-
son in the house.
Extension of the delay time by repeated pressing is not possible.
