When selecting switches for your project, we know that it can sometimes feel as though there is an endless list of options, features and attributes to sort through to make the right choice. Fortunately, we’re here to help you out.
The best place to start is to work out if you require panel mount or PCB mount switches, and then from there you can select the most suitable components. In this blog, we’re going to cover the key differences between panel mount and PCB switches, as well as their individual benefits, to help you get started.
What is a Panel Mount switch?
A panel mount switch is defined as a component that is inserted into a cut-out on a panel, with the actuator of the switch sitting on the outside and the body behind the panel. These components typically feature a threaded mounting nut or threaded bushing that is used to secure it to the panel, as well as wiring and/or connectors to connect to the circuit.
Some examples of where you might see panel mount switches in use include; lift/elevator button panels, door entry/exit points, film sets, coffee machines, boat controls or industrial panels.
The Benefits of Panel Mount Switches
1. Installation & Maintenance
Because they are installed in a panel and not welded to a circuit board, these switches are a lot easier to install than PCB switches and don’t require fiddly circuitry. Installation is made even easier if you purchase switches that come with wiring and/or connectors already attached. As the installation doesn’t require welding, this also makes it easier to maintain and replace switches, if and when the need arises.
2. Durability
Due to the way that they are installed, panel mount switches are held firmly in place, which makes them more durable than PCB components. Panel mount switches are designed to be quite rugged, and many are vandal-resistant and/or IP rated. This makes them better suited to applications where there is high usage/traffic, or in areas where they may face damage.
3. Bigger is Better?
As there are no limitations to what can fit on a circuit board, panel mount is the way to go if you require larger switches for your project. Larger switches can be beneficial, as they are more eye-catching and easy to use. This is especially helpful in situations where accessibility or safety are important. For example, emergency stop buttons need to be large and bright so that they can be quickly identified in the case of an emergency.
What is a PCB Mount switch?
A PCB mount switch is a switch that is directly mounted onto a PCB (Printed Circuit Board). These can be surface-mount (SMD/SMT) switches, which are designed to sit flat on the board, or through-hole/’thru-hole’ switches which are inserted into a hole on the PCB and soldered to the other side.
You can find PCBs in most electronic devices, as they can be made to an extremely vast array of specifications. Some applications that require PCB mount switches include; audio mixing desks, home automation, domestic appliances, entertainment systems and automotive systems.
The Benefits of PCB Mount Switches
1. Small but Mighty
As a PCB can be adapted to whatever size you require, the capacity and complexity of your interface design doesn’t have to be limited by size. PCB mount switches can be a lot smaller than similar panel mount options, both in terms of the actuator size, and the space required for wiring, etc. If you need to fit a lot of switches closer together in a small space, PCB mount is the way to go.
2. Versatility
The smaller size of PCB mount switches also means they can be more versatile in terms of design options. You can select from a wide range of styles, shapes and sizes for PCB switches, including RGB LED illuminated types and IP rated types, to create the best set up for your product. On top of this, at RJS Electronics, you can order custom caps and finishes for PCB switches, to create an even more unique switch for your project.
3. Quick Assembly
Whilst panel mount switches are easy to install, PCB switches are quicker to assemble, especially on a larger scale. Once you have mapped out where you want each switch to be on a PCB, this can cut down on the time it takes to connect each component in the right place. This PCB ‘map’ can then easily be replicated, so if you are producing a large quantity of your product, you can save on costs as well as time.
The Switches Compared
If you are still unsure whether Panel Mount or PCB Mount switches are better suited for your project, you can compare the switches themselves. Check out some of our most popular switches from each category:
Panel Mount Switches
Anti-Vandal Push Buttons
Metal, vandal-resistant push button switches in a wide range of styles. Choose high current, low profile, RGB illuminated or IP rated buttons in sizes from 6mm to 40mm.
Plastic Push Buttons
Bright, eye catching push button switches with a variety of colours, shapes and sizes. Multiple LED illumination options available, including split-face.
Navigation Switches
Multifunctional navigation switches and modules, designed to control movement by hand, either physically or digitally. Fully programmable types available with LCD/OLED screens.
Emergency Stop Buttons
Large, red e-stop push buttons to use in applications where an accident or emergency could be dangerous. Push-pull, twist release and key release types available.
Keylock & Selector Switches
Offering an alternative to push buttons, keylocks and selector switches feature multiple positions to allow for more precise control. Plastic, metal and LED options available.
PCB Mount Switches
Non-Illuminated Tact Switches
Compact push button switches that provide a tactile 'clicky' feedback when pressed. Smaller than other push buttons and requiring less force to operate.
LED Illuminated Tact Switches
Providing the same 'clicky' tactile feedback to the user, but with added LED illumination to clearly indicate when the switch is on. Available with a wide range of illumiantion options.
Pots & Encoders
Rotary potentiometers to adjust voltage within a circuit, and rotary encoders to control functions within the circuit. LED encoders are available, plus a range of knobs.
Relays
Automotive, communication and general purpose relays designed to control current in an electrical circuit, changing it from high to low current.
DIP & Slide Switches
Slide switches control the level of current within a circuit when the actuator is moved from side to side, while DIPs consist of multiple switches to change the operations on a device.
In Summary
Hopefully you are now more familiar with the key distinctions between panel mount and PCB mount switches. For applications that require large, rugged switches that are easy to install, your best bet is panel mount. But if you need smaller switches for electronic devices or products that will be manufactured to high quantities, PCB mount is the way to go.
