What is an Encoder switch? 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.Vertical or Horizontal?

Focusing on the smaller details can have a huge impact on the overall feel and look of the device. Including where key electro-mechanical components are placed within the wider design of the electronic device. Here, we have you covered, so you can continue doing what you do best. We have a selection of PCB, rotary encoders available in horizontal or vertical type. Our PCB encoder switches are up to 11cm in height and can support LED illumination.

To find out more about how we can custom our rotary encoder switches, speak to us directly. Our highly trained and knowledgeable Sales Engineers can put you in the right direction.

Bushing & Shaft Type

Our non-illuminated PCB, rotary encoder switches are available with bushing type. For more information contact us today or download the full PDF.

Our illuminated PCB, rotary encoder switch is available with ‘flat’ type or ‘knurled’ type of actuators. For more information contact us today or download the full PDF.

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

PCB, Encoder without LED Illumination. See more for actuators and levers. RJS Electronics Ltd.


Is our PCB rotary encoder available without LED illumination. This encoder is part of the RJS-Encode-11 series which have a range of actuators and available as horizontal and vertical encoder switches. This rotary encoder is ideal for devices to monitor or control a function, commonly suited for communication, audio, visual and broadcasting industries.  Find out more here.

Panel Mount, Encoder, SF39EB, RJS Electronics Ltd.


Is our metal, Panel Mount, rotary encoder. This switch is multifunctional as the rotary encoder function has a central push button switch. This switch function supports a momentary function. The central push button can be customised with custom etching and illumination options, such as power symbol. This multifunctional rotary encoder is ideal for a range of devices supporting navigation, control or monitoring a function, commonly suited for communication, audio, visual, broadcasting, automotive, medical devices, holistic therapy and spa devices.  Find out more here.

PCB, Encoder with Power Symbol, RJS-SFA, black encoder with illuminated or etched power symbol. RJS Electronics Ltd.


Is a PCB rotary encoder with a LED power symbol illumination. Another variation of this rotary encoder cap is available. See our ‘How to order’ section on the RJS-SFA product page. This rotary encoder cap is ideal for a range of devices to monitor or control a function, commonly suited for communication, audio, visual and broadcasting, automotive, medical equipment and spa industries.  Find out more here.


Is our latest panel mount encoder. This rotary encoder switch is a multi-functional device supporting the following features: a full TFT display screen, a push-button function, and a rotary encoder. This particular rotary encoder switch can be programmed using ‘raspberryPi’ or ‘Arduino’. This multifunctional encoder is ideal for a range of commercial and domestic devices and suitable for a range of industries such as aviation, automotive, medical, communication, and luxury spa devices.
