Switch & Button Operation Parts

Switch and button operation parts are simple controls you use to turn things on, turn them off, start a process, or stop it.
The Core Difference
The main difference between a switch and a button is how long they stay in their position:
• Switches (e.g., light switches, toggle switches): These stay in the position you put them (ON or OFF) until you physically move them back.
o Example: Flipping a light switch in your room—the light stays on.
• Buttons (e.g., a doorbell, remote control button): These are usually "momentary," meaning they only work while you are pressing them. They spring back to their original position when you let go.
o Example: Pushing a doorbell button—the bell only rings while your finger is on it.
Uses in Machines
These parts are crucial for giving humans direct control over machinery, and are found in many places, from household appliances to complex industrial control panels:
• Start/Stop: Green buttons often indicate "Start," while red buttons often indicate "Stop".
• Emergency Stops: Large, red "mushroom" buttons are used to quickly shut down equipment in an emergency for safety.
• Mode Selection: Rotary switches or toggle switches might be used to select between different functions or speeds.
• Basic Power: The simple "I" (on) and "O" (off) symbols often found on power switches are a universal standard.
