The circle indicates that the component has screw terminals and
a wire can be disconnected from it.
No circle indicates that the wire cannot be disconnected from
the component.
This indicates that the component has a wire connected to it
that is connected to ground.
This indicates that the component does not have a wire connected
to ground. It is grounded by being fastened to the machine.

FUSE - A component in an electrical circuit that will open the
circuit if too much current flows through it.
REED SWITCH - A switch whose contacts are controlled by a
magnet. A magnet closes the contacts of a normally open reed
switch; it opens the contacts of a normally closed reed switch.
SENDER - A component that is used with a temperature or pressure
gauge. The sender measures the temperature or pressure. Its
resistance changes to give an indication to the gauge of the
temperature or pressure.
RELAY (Magnetic Switch) - A relay is an electrical component
that is activated by electricity. It has a coil that makes an
electromagnet when current flows through it. The electromagnet can
open or close the switch part of the relay.
CIRCUIT BREAKER (C/B) - A component in an electrical circuit
that will open the circuit if too much current flows through it.
This does not destroy the circuit breaker and it can be reset to
become part of the circuit again.
SOLENOID - A solenoid is an electrical component that is
activated by electricity. It has a coil that makes an electromagnet
when current flows through it. The electromagnet can open or close
a valve or move a piece of metal that can do work.

MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an
electrical component that is activated by electricity and held
latch by a permanent magnet. It has two coils (latch and
unlatch)that make electromagnet when current flows through them. It
also has an internal switch that places the latch coil circuit open
at the time the coil latches.
