Switch (Normally Open): A switch that will close at a specified point (temp, press, etc.). The circle indicates that the component has screw terminals and a wire can be disconnected from it.

N

Switch (Normally Closed): A switch that will open at a specified point (temp, press, etc.).

No circle indicates that the wire cannot be disconnected from the component.

M

M

Ground (Wired): This indicates that the component is connected to a grounded wire. The grounded wire is fastened to the machine.

L

L

Ground (Case): This indicates that the component does not have a wire connected to ground.

It is grounded by being fastened to the machine.

The connectors shown in this chart are for harness to harness connectors.

Connectors that join a harness to a component are generally located at or near the component. See the Component Location Chart.

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.

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.

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 latched 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.
