This indicates that the component does not have a wire connected to ground. 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- Acom ponent that is used with a temperature or pressur e gauge. The sender  measures the temperature or pressure. Its resistance changes to give an indication to the gauge of the temperature or pressure. Relay (Magnetic Switch) - Arelay is an electricalcomponent that is activated by electricity. It has a coilthat makes an electromagnet when current flows through it. The electromagnet can open or close the switch part of the relay. Solenoid - Asolenoid is an electricalcomponent that is activated by electricity. It has a coilthat makes an electromagnet when current flows through it. The electromagnet can open or close a valve or movea piece of metalt hat can do work.
