Sender: A component that isused with a temperature or pressure gauge. The sender Sender: A measuresthe temperature or pressure. Its resistance changesto give an indication to the gauge of the temperature or pressure.

T

Relay (Magnetic Switch):   Arelayis an electricalcomponent thatisactivated byelectricity. It hasa coilthat makes an electromagnet when current flowsthrough it. The electromagnet can open or close the switch part of the relay.

Solenoid: Asolenoid Solenoid:  Asolenoid isan electrical component that isactivated byelectricity. Ithasa coilthat makesan electromagnet when current flowsthrough it. The electromagnet can open or close a valve or move a piece of metal that can do work. MagneticLatchSolenoid:  Amagnetic latch solenoid isan electricalcomponent that is activated byelectricityand held latched by a permanent magnet. Ithastwo coils (latch and unlatch) that make electromagnet when current flowsthrough them. It also hasan internal switch that places the latch coilcircuit open at the time the coil latches.
