2. 面板安装按钮开关的机制如何运作？

The panel mount push button switch operates to connect or disconnect one or more circuits that initiate the device or equipment function.

It requires manual force, such as pressing or touching the actuator, to move the internal mechanisms of the switch, thereby opening or closing the circuit and controlling the current flow.

What constitutes the assembly of a panel mount push button switch?

The panel mount push button switch consists of two main components: the actuator and the body or enclosure.

However, besides these main parts, other components are equally important for the operation of the panel mount push button switch.

The following are the most common assembly parts of a panel mount push button switch:

• Actuator – Also referred to as the panel mount button, operator, or head, it is the user-facing part of the switch that is pressed to initiate the designated operation.
• Enclosure – Also known as the shell or body, it houses and protects the internal mechanical and electrical components of the switch.
• Terminals – Also called pins, these are the points where wires are typically connected to the switch.
• Mounting flange – Generally a hex-shaped nut used to fasten and secure the panel mount push button switch in place.
• O-Ring – Also known as a rubber ring or rubber seal, it is positioned beneath the actuator to seal the panel cutout and prevent water ingress when mounted.
• Grooves – These are indentations around the body of the switch that allow the mounting flange to fasten it tightly.

The interior of the panel mount push button switch contains a spring, fixed and movable contacts, and an LED chip for illumination.

Some types of panel mount push button switches, such as piezo switches, have no moving parts and instead contain an assembly module.

What are the styles and purposes of panel mount push button switches?

Panel mount push button switches are also classified by style and purpose.

This classification addresses issues such as accidental button presses by stray fingers or activation by objects inadvertently bumping into the switch.

This solution is particularly important when the switch's purpose relates to security, safety, and critical processes.

• Extended application.
  • The actuator is raised higher compared to other standard raised button heads.
  • Typically used for the “stop” function in machinery.
• Flush application.
  • The actuator is flush with its enclosure, meaning direct pressure is required to actuate the switch.
  • Commonly preferred for “start” functions, such as in push-button start panels.
• Selector switches application.
  • Used when multiple control options are required.
  • Employed for maintained contact applications.
• Guarded application.
  • This further prevents unwanted operation, as the actuator is surrounded by a metal guard.
• Mushroom and Jumbo mushroom application.
  • These are generally used for emergency stop and stop push buttons.
  • They are very easy to operate, making them ideal for emergency situations.
• Push-pull operators.
  • The actuator must be physically pushed and pulled to turn the switch off and on.
  • Typically used for two-position maintained contacts (e.g., start/stop or up/down buttons) or three-position maintained or momentary contacts (e.g., start, stop, run buttons or hand, off, auto functions).
• Twist to release application.
  • In this application, the actuator is activated by pushing it in and then twisting to release.
  • Generally used for «emergency stop» or «stop» functions in machinery.
• Key release application.
  • Similar to twist to release, but requires inserting a key to release the actuator.
  • Often used for safety purposes, such as locking a machine during maintenance procedures.
• Illuminated lens or operator.
  • This combines push-button functionality with an indicator light, saving space and cost for the user.
  • Although the push-button and indicator light are integrated into one device, they are wired separately to function.
• Roto push application.
  • This application combines the push button and selector switches in one device.
  • The push button has an outer guard that can be rotated to multiple positions which can provide several contact actions whenever the actuator is pressed or released.
• Potentiometer
  • This is often used as a control for speed since it can vary resistance by turning its dial.
• Joystick application
  • The buttons are mounted in a standard hole size with some space left behind the panel for the lever to work.
• Square operator with multifunction application
  • This is used when there are several functions required and space is at a premium.

7. What are the switch actions of the panel mount push button switch?

The panel mount push button switch can be categorized into two different switch actions which are the following:

• Panel mount momentary push button switch – In this switch action, the actuator remains depressed while it is being pressed down and it springs back into its normal state when the pressure is released.

It is also called the panel mount momentary switch, panel mount momentary push button, panel mount momentary push button switch, flat momentary switch, and momentary switch panel.

• Panel mount latching push button switch – In here the actuator remains depressed even after releasing the pressure and will only return to its normal state when it is pressed again.

Momentary panel mount push button switch application

8. What are the switch starting positions of the panel mount push button switch?

The panel mount push button switch momentary and latching switch actions have two kinds of starting positions or contact states, and they are:

• Normally open panel mount push button switch – In this starting position, the contacts are always open until the actuator is pressed down which connects the contacts and allowing the current flow.
• Normally closed panel mount push button switch- In here the contacts are always closed and the contacts are connected until the actuator is pressed down that disconnects them.

Some of the examples are the following:

• Off
• Off or On
• 1 Off (Normally Open)
• 1 Off (Normally Open) and 1 On (Normally Closed)
• 1 Off (Normally Open) or 1 On (Normally Closed)
• 1 On (Normally Closed)
• 2 Off (Normally Open)
• 2 Off (Normally Open) and 2 On (Normally Closed)
• 2 Off (Normally Open) or 2 On (Normally Closed)
• 2 On (Normally Closed)
• 3 Off (Normally Open)

9. What are the electrical industry designations of the panel mount push button switch?

The panel mount push button switch also has electrical industry designations or in simple terms, electrical control circuit classifications or contact forms.

These are the poles and throws of the panel mount push button switch.

Most of the time, people tend to define the poles by the number of the switch’s terminals but this is not the definition of the term at all.

The poles refer to the number of circuits that a switch can control.

For example, a single pole controls one circuit, two poles control two circuits within one unit, and so on.

There are four basic contact form variations and these are the following:

• Single Pole Single Throw (SPST)
  • This is also known as the two way switch or on and off switch.
  • It controls the connection and disconnection of two terminals.
  • It can only have one “on” position.
  • For example, push button on off panel.
• Single Pole Double Throw (SPDT)
  • This is also known as the A/B switch.
  • This has one input terminal and two “on” positions.
• Double Pole Single Throw (DPST)
  • Has the ability to control two circuits.
  • There are two inputs and two «on» positions.
• Double Pole Double Throw (DPDT)
  • Can control two electrical circuits with two input terminals and two selections for the output terminals.
  • Can be configured as a single pole.

10. Why do most panel push button switches are made from stainless steel?

Stainless steel is one of the iron-based alloys which contains some amount of chromium to make it rustproof and heat resistant.

Other types of stainless steel include some amounts of carbon, aluminum, nitrogen, silicon, titanium, sulfur, copper, molybdenum, niobium, nickel, and selenium.

Most panel mount push button switches are made from stainless steel and this is because stainless steel is a durable material.

There are over 150 stainless steel grades but panel mount push button switch manufacturers generally use two kinds of grades only which are grades 304 and 316.

• 304 stainless steel grade – This grade has some amount of nickel and chromium which makes it high temperature resistant and high density.
• 316 stainless steel grade – This grade has molybdenum included which makes it resistant to high temperatures and rust.

While stainless steel is the most preferred material for panel mount push button switches, other materials are also used such as the following:

• Anodized Aluminum
• Silver alloy
• Gold and nickel-plated brass
• Gold and silver-plated copper
• Silicone
• Ceramic
• 聚碳酸酯
