Switch(NormallyOpen): A (NormallyOpen): A switch that will close at a specified point (temp, press, etc.). The circleindicatesthatthe componenthasscrew terminalsandawirecan bedisconnectedfromit. Switch (NormallyClosed ):  Aswitch that will open at a specified point (temp, press, etc.). Nocircleindicatesthat thewirecannotbedisconnectedfromthecomponent. Ground (Wired): This (Wired): This indicates that the component is connected to a grounded wire. The groundedwireisfastenedtothe machine. Ground (Case):  T hisindicatesthat thecomponentdoesnothavea wireconnectedtoground. It is grounded by being fastened to the machine. Reed Switch:  Aswitch whose contacts ar e controlled by amagnet. Amagnet closes the contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch.
