Delivers maximum starting
power: allows either or
both batteries to be used.
Can be switched between
batteries even when the
engine is running.
Rugged polyester thermoplastic case and knob.
Stands up to impact,
maintains its water-resistant
integrity.
High-performance synthetic

Mounting
M-750 series switches can be mounted flush or
from behind, through a circular hole. When mounted
flush, the switch covers over any holes previously
made for other brands of battery selector switch.
When mounted from behind, No. 563 self-adhesive
plastic sticker is
