COMBINATION CONTROLS

Fuse: A component in an electrical circuit that will open the circuit if too much current flows through it.

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

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.

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

Ground (Case): This indicates that the component does not have a wire connected to ground.It is grounded by being fastened to the machine.

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.
