Common Types of Push Button Switches

Push button switches can be classified in several ways, including function, operation type, structure, material, illumination, and protection level. Below is a clear industrial overview suitable for technical or website use.

1. By Function

1) Start Push Button

Used to start machines or activate systems.

Usually green or blue
Typically NO (Normally Open) contact

Applications: industrial machines, control panels, automation systems

2) Stop Push Button

Used to stop equipment operation.

Usually red
Typically NC (Normally Closed) contact

Applications: machinery control systems, electrical panels

3) Emergency Stop Button (E-Stop)

Used for immediate shutdown in dangerous situations.

Mushroom head design for easy pressing
Latching mechanism (twist or key reset)
High safety rating (IP65/IP67/IP68 options)

Applications: robots, production lines, EV charging stations, industrial equipment

4) Reset Button

Used to reset systems or clear alarms.

Momentary operation
Low-current signal control

Applications: electronic systems, control circuits

2. By Operation Type

1) Momentary Push Button (Self-Resetting)

Active only while pressed
Returns automatically when released
Most widely used type in industry

2) Latching Push Button (Self-Locking)

Stays in ON/OFF state after pressing
Press again to change state
Used for power control or mode switching

3. By Structure Design

1) Flush Type Button

Flat surface design
Reduces accidental activation
Common in industrial panels

2) Raised Type Button

Prominent surface
Clear tactile feedback

3) Mushroom Head Button

Large surface area
Designed for emergency operation
Common in safety systems

4. By Material

1) Metal Push Button Switch

Stainless steel / aluminum / nickel-plated brass
High durability and corrosion resistance
Suitable for industrial and outdoor environments

2) Plastic Push Button Switch

Materials: ABS / PA66
Lightweight and cost-effective
Suitable for general applications

5. By Illumination

1) Non-Illuminated Button

Basic on/off function
No indicator light

2) LED Illuminated Button

Built-in LED indicator
Colors: red, green, blue, white
Shows machine status clearly

3) Ring Illuminated Button

Even circular lighting effect
Premium appearance
Common in EV chargers and high-end equipment

6. By Protection Level

1) Standard Type (IP40 / IP54)

Suitable for indoor environments

2) Waterproof Type (IP65 / IP67 / IP68)

Dustproof and waterproof
Suitable for outdoor and industrial harsh environments

Summary

Push button switches are widely categorized into start, stop, emergency stop, and reset types, and further divided by operation mode, structure, material, lighting design, and protection rating. These classifications help engineers select the right switch for different industrial applications.
