More information
Mechanical storage
Remote control switches are used to switch lighting by means of
several pushbuttons. This makes complex cross/two-way
switching unnecessary. With each pushbutton impulse, the
remote control switch changes its contact position from OFF
to ON, etc. In the event of a power failure, the last switching
position is mechanically stored. Electromechanical remote
control switches have no standby loss.
Pushbutton malfunction
Pushbuttons can jam, which may expose remote control switches
to a continuous voltage. All remote control switches are protected
against this type of malfunction through their design or through
PTC.
Central switching functions
Versions with central ON/OFF functions allow the central switching
of all connected remote control switches, which can also be carried
out over a clock timer.
All remote control switches can be switched to the ON or OFF
switching state, regardless of their current switching state.
Contact sequences
0 – 1 – 2 – 1
+2
or
1 – 0 – 2 – 0
means:
0:
No contact closed
1:
Only contact 1 closed
2:
Only contact 2 closed
1
+2: Contact 1 and contact 2 are closed
The contact positions are constantly changing with each
pushbutton impulse.
