KEYSWITCH TERMINATIONS
The standard panel keyswitch can be
used to tap off a switched positive
ignition feed to power additional
gauges. In this way these gauges will
only be live whilst the engine is
running, the engine is starting or the
heaters are being used.
For silver keyswitches, the terminal to
achieve this ignition switched positive
is marked ' A C'.

Typical Battery Capacity
(AH) at a 20hr Rate

65~ 75
For black keyswitches, the terminal to
achieve this ignition switched positive
is marked '15/54'.
For panels without any keyswitch,
gauges can be driven from the 1mm
brown wire which teriminates at 11
way connector terminal 4. This is a
lower power switched positive, any
additional power required from this
connection must be feed through a
relay, as noted below.

Note: these keyswitch terminals are
rated at 10 amps maximum, since
they are already utilised for panel and
alternator feeds Beta Marine
recommend any additional
requirements from these terminals
must be fed through a relay. This
relay should then be connected to it's
own fused positive supply directly from
the engine battery.

pump with ignition switched relay can
