Let’s start by selecting the function of the switch.
Momentary and Latching function applies to a wide range of our PCB and panel mount switches; including push buttons, keylock & selector switches, rockers, toggles and more.
Momentary Switches
The circuit of a momentary push button switch is only connected when it is pressed, which means that the button will immediately return to its natural state when it is released. A common example of a momentary switch would be a doorbell.
Latching Switches
A latching (or maintained) push button switch remains in a position when pressed, and must be pressed again to release it. This means that the circuit remains open or closed until the switch is pressed again. Light switches are the most common example of a latching switch.
RJS Electronics Ltd distributes a range of plastic and metal push button switches that are available with or without LED Illumination and can support momentary and latching functions. Many of our push button switches are listed as momentary and latching, giving our customers a choice out of the two.
See the full product range of our PCB and Panel Mount switches which support Momentary or Latching function.
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.
Configurations
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
We have a range of switches that 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.
IP Rating
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 ratings.
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.

LED Illumination
Does your anti-vandal switch require single/bi-colour or RGB LED illumination?
We offer many types of LED illumination, including dot or ring illumination. Or if you’re looking for something custom, LED symbols and text can be added. See the available colour LED options listed on the full product specifications and single product pages.
If you require more information about the available LED illumination options, speak to our Sales team directly!
