SIGNAL CONTROL SWITCH ASPSW1
The ASPSW1 is used to manually operate multi-aspect led signals from a control
panel position using a rotary switch. Matching panel mounting kits containing legend
plates, control knobs and screws are available separately.
The lit aspects to be shown by the attached led signal can be selected using a
rotary knob at the control panel
When moving through positions with the switch, signal changes are
supressed until a final selection is made
All changes to the aspects shown by the signal are made using progressive
fading to simulate the use of filament lamps in the signal (can be turned off).
Additional leds can be fitted to the control panel to mimic those on the layout.
No resistors are required simplifying wiring as the module provides a stable
output to feed the attached signal
Requires a 12V DC Power Supply

The module has been fitted with a control panel legend plate and control knob. As well as the attached signal, “repeater” leds can be fitted to the control panel and wired to the module so the status of any signal out of view of the operator can be confirmed.

  • Page 8 BLOCKsignalling www.blocksignalling.co.uk Programming There is no necessity to reprogram the module, but there are a small number of adjustments available to the user to change how the module operates. Programming is performed by holding down the Push Button when switching on the power and counting flashes of the led on the board..

    Align the knob with the most anticlockwise legend, and push the control knob back into place. Q. How many ASPSW1 modules can I power from my 12V DC power supply ? A. The module consumes less than 0.02A (20mA), so with a 1A power supply it should comfortably be possible to operate 50 or more modules.
