Switch (NormallyOpen): Aswitch that will close at a specified point (temp, press, etc.). The circleindicatesthatthe componenthasscrewterminalsandawirecan bedisconnectedfromit. Switch (NormallyClosed ): Aswitch that will open at a specified point (temp, press, etc.). Nocircleindicatesthat thewirecannotbedisconnectedfromthecomponent. Ground (Wired): Thisindicatesthat thecomponentisconnectedtoa groundedwire.The groundedwireisfastenedtothe machine. Ground (Case): Thisindicatesthat thecomponentdoesnothavea wireconnectedtoground. It is grounded by being fastened to the machine. Reed Switch: Aswitch 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 componentthatisusedwitha temperatureorpressuregauge.Thesender measuresthetemperatureorpressure.Itsresistancechangestogive anindicationto thegaugeofthe temperatur eorpressure. Relay(MagneticSwitch ): Arelay is an electrical component that is activated by electricity. Ithasa coilthatmakesan electromagnetwhencurrentflowsthroughit.The electromagnetcanopenorclosetheswitch partoftherelay. Magnetic Latch Solenoid: Amagnetic 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) thatmakeelectromagnetwhencurrentflowsthroughthem.Italsohas aninternalswitchthatplaces the latch coil circuit open at the time the coil latches. Solenoid: Asolenoid is an electrical component that is activated by electricity. It has a coilthatmakesan electromagnetwhencurrentflowsthroughit.The electromagnet can open or close a valve or move a piece of metal that can do work. 1 2 AG-C4 111-7898 L-C12 3E-5179 9X-1123 Component Part Number Pin orSocket Number Part Number:for Connector Receptacle Part Number: for Connector Plug Harness Identification Letter(s): (A, B, C, ..., AA, AB, AC, ...)
