Find out more about our wide range of  ‘Encoder Switches’

In this blog post, we aim to give you a detailed guide about our wide range of  PCB (printed circuit board) and selection of  Panel Mount, encoder switches which support a range of, actuator heads and levers with LED illumination or etching options. Many of our electromechanical components can be customised including our Pots (potentiometers), Knobs and Encoders. An encoder switch is usually an electromechanical component that transfers information through a motion to command change within a larger electronic device. An encoder switch can be used to control a function or factors such as volume, temperature and speed (but not limited to these factors). An encoder can be a device, circuit, software programme to transfer information or PCB electro-mechanical component that is used for control.

Our wide range of Encoders is electromechanical components ideally used to select function and control or monitor a function. We have a wide selection of PCB encoders and panel mount encoders which commonly share a rotation feature and/or push button function. Additionally, many of our rotary encoder switches have a momentary push button function, this can be used to ‘Push to make’ or ‘Push to break’, either selecting a function that the device is monitoring or controlling.

Encoder switches which require motion to initiate change are rotary encoder switches. The rotary mechanism will either increase or decrease the operation as rotary encoder switches are used to monitor or control, a wide range of mechanical systems, industrial controls, robotics, photographic lenses, communication devices within commercial and domestic vehicles.

RJS Electronics supplies a range of PCB, rotary Encoders which are designed to control factors within an electronics device through rotation and push-button selection.

Here’s how to locate our encoders on our website.

Our range of ‘Encoders’ explained …

Here is how we have categorised our ‘Encoder’ switches.

PCB or Panel Mount?

Our PCB Encoders switches can be directly mounted (Printed Circuit Board). Surface mount PCB encoder switches (SMD/SMT) are designed to sit flat and directly on top of a PCB. Through-hole or ‘thru-hole’ PCB encoder switches are inserted into a drilled hole on the printed circuit boards and soldered to pads on the opposite side. For more information on our range of PCB push button switches and electro-mechanical components switches here.

However, Panel Mount switches are designed to for the device slightly differently as these components are designed to be inserted from below through the area cut. A panel mount component will sit behind or on top of a panel, sitting outside an enclosure. See our guide to panel-mount switch pins here. For our range of panel mount switches click here.

Here are a selection our PCB and Panel mount encoder switches.
