Mounting the reed switches inside the ash pan, when using Radio Shack magnets:
1.
Remove the two screws that hold the ash pan in place on the bottom of the
engine. Also remove the center screw that holds the engine's PC board in place.
This allows you to remove the ash pan cover from the engine.
2.
For installation of the switches, orient the ash pan so the silver side is face up as
shown in the diagram on the next page. (The outside of the pan is black and the
inside is silver-colored. )
3. We mount the bell activating reed switch on the fireman's side of the engine and
the whistle activating switch on the engineer's side. The bell switch is mounted
Your Bachmann Shay BIG SOUND™ kit includes a toggle switch for volume control
and two reed switches that can be used with track magnets if you prefer to hear the
whistle and bell at specific locations on your layout. (The chuffing reed switch and the
DIP switch—which are standard kit components for other sound selections— are
not needed for the Bachmann Shay installation.)
Reed Switches
If you choose to use magnets on the track for bell and whistle activation at specific
locations, you will need to mount the reed switches on the underside of the engine.
We believe most operators will use either our speed-controlled, programmed sound
sequence or a remote activation system, such as Locolinc® or Digitrax.® However,
we have included two reed switches in the Bachmann Shay BIG SOUND™ kit in case
you choose to use them. Here are our tips and suggestions for mounting the optional
reed switches on your Bachmann Shay.
If you decide to use LGB magnets, the reed switches would be installed in a horizontal
position on the underside of the engine on the ash pan since the LGB magnets are
not particularly strong. If you want to mount the switches out of sight inside the
engine's ash pan, you should choose stronger ceramic magnets such as Radio Shack
model 64-1879 or model 64-1883. In our tests, the LGB magnets did not trip the
reed switch mounted inside the engine in a consistent manner.
