Switch(NormallyClosed): Closed): Aswitch that will open at a specified point (temp, press, etc.). Nocircleindicatesthat thewirecannotbe disconnectedfromthecomponent. Ground(Wired): (Wired): This indicates that the component is connected to a grounded wire. The groundedwireisfastenedtothe machine.
Ground(Case): (Case): This indicates that the component does not have a wire connected to ground. It is grounded by being fastened to the machine.
ReedSwitch: Aswitch Switch: Aswitch whose contacts arecontrolled by a ma gnet. Amagnet closes the contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch.
Sender: Acomponent Acomponent that is use d with a temperatu re or pressure ga uge. The sende r measures the temperature or pressure . Its resistance changes to give an indication to thegaugeofthe temperatureorpressure.

Relay(MagneticSwitch): Arelay is an electricalcompo nent that is activated yb electricity. It has a coilt hat makes an electromagnet when current flows through it. The electromagne t can open or close the switch part of the relay. Solenoid: Asolenoid is an ele ctricalcomponent that is activate d by electricity. It has a coilthat makes an electromagnet when current flows through it. The electromagne t can open or close a valve or move a piece of metalthat can do work.

MAGNETICLATCHSOLENOID- Amagnetic latch solenoid is an electricalcomponent 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 internalswitch that places the latch coilcircuit open at the time the coillatches.

MAGNETICLATCHSOLENOID- Amagnetic latch solenoid is an electricalcomponent 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 internalswitch that places the latch coilcircuit open at the time the coil latches.
