Toggle switch
(9) An external source of direct current electrical power is connected to the receptacle at the upper right rear corner of
the quadrant housing. A three-position, center OFF, toggle switch mounted through the bottom of the housing controls current
to the branch of the circuit serving counter and level LEDs and the branch serving the extension light. The latter assembly is
held by a spring clip behind the housing and connected by a wiled cord and bayonet locking connector to a receptacle at the
lower, left, rear corner of the housing. Spring contacts connect electrical cables in the housing to those in the cover leading to
counter and level LEDs, thus permitting removal of the cover assembly without disconnecting cables. Watertight, bayonet
locking metal caps cover level LEDs and an overlay assembly containing LEDs covers the counters.
