Momentary & Latching Push Button Switches

momentary and latching push button switches with or without LED illumination, PCB and Panel Mount Switches, RJS Electronics Ltd.

A Push Button switches, metal or plastic have types of function when pressed, the push button switch is either Momentary or Latching. RJS Electronics Ltd distributes a range of plastic and metal push button switches with or without LED Illumination, support both ‘momentary’ and ‘latching’ functions. These are key functions of a PCB and Panel Mount push-button switches when pushed.

Latching Push Button switch:

A latching push button function also referred to as maintained, means that it remains in a position until pressed again. It required to be pressed down or touched multiple times to either turn on or off the device or function. It aims to push to make and push to break a cycle and can also be referred to as normally closed push switches.

 

Momentary Push Button Switches:

A Momentary push button function means that when pressed down, it immediately returns to its natural state. For it to either change the function, it’s required to be touched or pressed.

How to read our part numbers to ensure that you find the right switch for your design.

Here is a key, RJS – majority of our part numbers begin with RJS because they are ours.

Next, the combination of Numbers or Numbers and Letters suggest the – The series they belong to, the contact or number of resistors.

Followed by the sizing. Our metal push button switches and indicators are pre-categorised into sizes and available between 6mm – 42mm. The number will indicate the size.

Sometimes, you will notice that there is a letter or letter and (A) which will indicate the function. For example, a part number followed by no letter(s) indicates momentary only [see below].

RJSX02-16LA-H-D~67Q

Whereas,  an ‘L’ next to the number will suggest that the product is Latching only [see below].

RJSX02-16LA-H-D~67Q

And, if there is an ‘L(A)’ next to the number this will indicate that the product is available in both, momentary and latching functions.

RJS107-16L(A)-F-C5~67J

Not only Push button switches here a few other components which support momentary or latching function:

PS909L-62-2-K

SPC Square

SPD5K2

Here are some other key factors to consider when placing an order:

Mounting style: Any switch is designed to be compatible with a variety of circuit setups. Our PCB switches are available as SMD (surface mount meaning they sit directly on top) or THT (through-hole meaning they are threaded through) style. Alternatively, Our Panel Mount switches are designed to be placed directly within the circuit.

IP Rating: Let us give you a break down of the IP ratings. Click to save or screenshot the table, for future reference. Many of our PCB and Panel mount switches are IP rated. For more information about IP ratings, click to read our blog about IP rating. https://www.rjselectronics.com/blog/2019/blog-rjs/ip-ratings-explained/

 

IP65 Rated

 

Dust tight, protected against water projected from a nozzle.

 

 

IP66 Rated

 

Dust tight and protected against powerful water jets.

 

 

 

IP67 Rated

 

Dust tight, protected against water immersion for 30 minutes between depths of 150mm to 1000mm

 

 

IP68 Rated

 

Dust tight and protected against continuous water immersion.

 

All our switches are IP rated (from the front) which means that our Slide switches are sealed and/or waterproof, making them hardwearing and durable in a range of conditions.

Configuration:

By configuration, we are referring to ‘Poles and Throws’. A switch will have two terminals for the current to flow through, to come in and come out. The Poles and Throws determine how many separate circuits the switch can control and the Poles indicate how many switch poles It can be connected to.

Pole and Throw Configurations

RJS Electronics - SPDT explained

We have a range of switches which support a range of configurations which are commonly referred to as single pole and double pole. The poles and throws indicate the number of circuits that are controlled by the switch. The throw defines how many positions the switches poles can be connected to.

  • SPSP – single pole single throw
  • SPDT – single pole double throw
  • DPST – double pole single throw
  • DPDT – double pole double throw
  • 3PDT – Three poles double throw
  • 4DPDT – Four poles double throw

SPST switches make or break the connection of a single conductor in a single branch circuit. This switch type typically has two terminals and is referred to as a single-pole switch.

SPDT switches make or break the connection of a single conductor with either of two other single conductors. These switches usually have three terminals and are commonly used in pairs. SPDT switches are sometimes called three-way switches.

DPST switches make or break the connection of two circuit conductors in a single branch circuit. They usually have four terminals.

DPDT switches make or break the connection of two conductors to two separate circuits. They usually have six terminals are available in both momentary and maintained contact versions.

LED Illumination:

Now you’ve selected the key features of your anti-vandal push button metal switch, here are some additional features you may need to consider…

Does your anti-vandal switch require LED illumination? If so… does it require a ring/dot/power symbol or custom illuminated LED illumination?

antivandal, metal push button switch, panel mount, LED illumination, non- illumination, RJS Electronics Ltd, push button switch, Single LED illumination, Bi-colour LED Illumination, RGB Illumination, ring LED illumination, dot illumination, dual illumination, power symbol, custom options available RJS Electronics Ltd.antivandal, metal push button switch, panel mount, LED illumination, non- illumination, RJS Electronics Ltd, push button switch, Single LED illumination, Bi-colour LED Illumination, RGB Illumination, ring LED illumination, dot illumination, dual illumination, power symbol, custom options available RJS Electronics Ltd.High current metal anti vandal push button switch with power and ring led illumination. Select from momentary function push button switch or Latching push button switch, Latching function. RJS electronics ltd

Sticking with LED illumination does you anti-vandal switch require single/bi-colour or RGB LED illumination. See the available colour LED illumination options listed on the full product specifications and single product pages. If you require more information about the available LED illumination option, speak to us directly!

Moving from the LED illumination options, here are some additional technical features may need to consider when selecting the correct anti-vandal switch.

What kind of terminals does your application design require? Many of our anti-vandal switches have solder lug terminals meaning ….

Another technical feature to consider is the voltage. All our anti-vandal, metal push button switches are available with 5V/12V and 24V.

RJS Electronics Ltd, Slide switches are commonly used in many applications for larger industrial controls or smaller hand-held or battery-operated devices. The application can include consumer electronics, instrumentation, computer servers, test and measurement.  They come in single or double pole options and have multiple actuator height options and offer a range of IP rating to protect from dust and water.* Here are some of the application Slide switches are used for and suitable for, but not limited to.

Applications:

  • Audio
  • Broadcast
  • Beauty
  • Medical
  • Industrial Controls
