Electromechanics Flashcards
Toggle Switch
Simple switch which flips back and forth between two positions
Poles
Independent sets of contacts that are switched in parallel by the same lever
Slide Switch
Completes the circuit by sliding a terminal
Push button Switch
‘Normally open’ switch (open unless button is being pressed)
DIP Switch
Rocker switches in the classic dual in-line package
Tactile Switch
Often used as responsive buttons on electronics and appliances (like an eject button on a DVD player); often hidden behind larger, customised buttons
Microswitch
Remarkably reliable, designed to work for millions of cycles; gives clicky feel (think computer mouse buttons)
Electromagnetic Relay
Switches that are actuated by electrical signals, rather than by a button or a lever; robust, low-cost method of switching substantial electrical power
Solenoid
A type of inductor specifically used as an electromagnet
Thermal Switch
Opens and closes at a given temperature
Bimetallic Strip
Welded sandwich of two dissimilar metals with different rates of thermal expansion
Stator
Permanent magnet
Commutator
Ensures that the current only flows in one direction
Stepper Motor
Optimised for starting and stopping quickly in precise rotational increments called “steps” rather than continuous rotation
Magnetic Buzzer
Used in many kinds of equipment to make all sorts of noises; tone produced through current-induced vibration
