One thing to note about adding the BT-005 to your player is that it will require
drilling some holes in top of the spoolbox. If you are not comfortable modifying
your player system, then you can consider making a replacement top that will fit
on the spoolbox and keep the original unmodified.
Everything needed to install the switch is included. The ultra sensitive micro-switch
is rated at 10 Amps and is compatible with all vacuum box products. The included
cable plugs right into the BT-002 pump kit without any wire cutting or splicing.
A fully detailed instruction manual walks you through the installation and wiring.
The BT-005 measures 3” x 1.25” x 1.25”.
Introducing the BT-005 Auto shut-off switch by Bergytone Products. This switch is
used to sense the end of rewind and automatically shut off the vacuum pump system.
It is identical to the PPCo part number 652, and is a direct replacement for this
part at a lower cost.
One of the common problems that player pianos with electrification kits have is that
at the end of the rewind cycle the roll spins in the spoolbox. It will stay this
way, making a whole bunch of racket until someone finds the main power switch and
shuts the pump off. The BT-005 senses the end of the rewind and automatically shuts
the pump off.
The BT-005 has a tab (actuator) that hangs down behind the roll and when the roll
finishes rewinding, the action of the roll tab flapping in the spool hits the tab
and shuts the switch off. A small push button resets the switch and starts the playing
over again. There is nothing in contact with the paper roll as it plays.
A disconnect plug is provided to allow for later removal of the upper part of the
player system for servicing or tuning. An eight foot extension cable is provided.
