MR323 ON - ON or ON - OFF
This switch module can be used for Track Isolation, or Track
switching, 2 Aspect Signals, Building or Street lighting, in fact for
any equipment that requires an ON – OFF switch
THIS SWITCH UNIT REQUIRES NO EXTRA WIRES, NO SENSORS, NO SOLDERING - TO GIVE YOU A SWITCH WITH STATUS INDICATION & REMOTE INDICATION -  JUST THE WIRING YOU WOULD NORMALLY DO.
It can be used for any either/or situation such as red or green indication. The module is fixed in place by the switch. The LED is set at 20mm from the centre of the switch, and at the correct height not to require an LED mount, just a 5mm hole. The Switch modules can be set 28mm apart to create a bank of switches. The switch circuit is completely independent of the Indication circuit.
