Emergency Stop Switch

A push button switch is a simple mechanical device that controls an electrical circuit by pressing or releasing an internal contact.
Main Types of Push Button Switches
• Momentary Switches: Connect or disconnect the circuit only while you hold the button down, returning to the default state upon release (e.g., doorbells, computer power buttons).
• Latching (Maintained) Switches: Change state when pressed and stay in that position until pressed a second time (e.g., clicky pen mechanisms or certain power switches).
• Normally Open (NO): Keeps the circuit open (off) at rest and completes the circuit when pressed.
• Normally Closed (NC): Keeps the circuit closed (on) at rest and breaks the connection when pressed.
Common Uses
• Electronics & Arduino: Small tactile switches (like 6x6mm buttons) are used on breadboards for prototyping.
• Appliances & Industrial: Panel-mounted buttons control heavy machinery, control panels, and safety emergency stops.
• Local Availability: You can find basic and specialty switches locally through online platforms like Da
