19-Switch DualSense Interface | PS5

The 19-switch DualSense interface from OneSwitch enables you to use accessibility switches alongside the included DualSense controller to play on a PlayStation 5 (PS5) console. In this post we will look at its features and some of the instances it may be used.

The 19-switch DualSense interface is a modified DualSense controller, that has an external box connected to it by a cable and has switch ports (3.5 mm) for the inputs on a PS5 controller. It has switch ports for the following controller inputs: D-pad, Cross, Circle, Square, Triangle, L1, L2, L3, R1, R2, R3, Left Stick Up, Create, Touchpad button and Options. 

What is a ‘switch’?

An accessibility switch is a piece of hardware that can be used to as an alternative input for a game controller button or keyboard key, for example, depending on the interface it is used with.

They are often connected to a compatible interface via a connected cable, that is pushed into a socket (port) on the interface to connect it. They are available in different shapes and sizes, requiring different types of activation and/or different amounts of force to activate them.

They can often be positioned where it is most accessible and comfortable for a user to activate them, such as by a finger or hand, or by the head or foot. Examples of a few different switches from the Logitech G Adaptive kit for Access controller can be seen in the image below:

At SpecialEffect we use accessibility switches in almost all of the controller set-ups we create with the people we work with. We use them as inputs for button, trigger and/or stick directions. We sometimes just add one or two, but often use multiple switches in our controller set-ups, sometimes needing to use a switch for almost every button and trigger input on a controller.

Ways to use the 19-Switch DualSense interface

If a player is able to use some of the inputs on it, the connected DualSense controller can also still be used alongside any connected switches, as all of its inputs remain functional. For instance, a player may use the left side of the connected DualSense controller with their hand, but use switches to control the inputs that are found on the right side of the controller. This could also allow a second player to share the controls to play cooperatively – with one player using the DualSense alongside another player using switches.

It could be paired with an additional DualSense controller using the PlayStation 5 console’s ‘Use Assist Controller‘ option, if a player wanted to split the control inputs across the two controllers to use them with different parts of their body, or share the controls with another player and play cooperatively with one DualSense controller each. 

It could also be paired with one or two of Sony’s Access controllers to supplement the available control inputs and switch ports available on those. Such as when a player needs more switches than are available on them. The Access controller itself includes four 3.5 mm ports alongside the included customisable buttons and an analog stick, with a total of eight switch ports if you pair two Access controllers together.

Two external Celtic Magic joysticks are also connected to the Access controller. The joysticks and switches are placed on two Logitech G hook and loop boards.

For instance, if a player uses two external compatible joysticks with an Access controller, they will have two ports left for switches, or six if they use two paired Access controllers. For some players this will be enough switches to use alongside the included button inputs on the Access controller, or a paired DualSense, but some players may need more than this to play the games they want to play.

Comparing the 3.5mm ports with those on the Access controller

The Access controller’s 3.5mm ports also allow players to connect compatible external analog sticks, which the 19-switch DualSense interface does not. The same types of switches can be used with both, excluding the Logitech G Variable Triggers that come in their Adaptive Gaming Kit, these will not work with the 19-switch DualSense interface.

Amongst the 19 ports, the 19-switch DualSense interface includes a switch input for Left Stick Up, allowing players to use an accessibility switch for forwards movement in-game. This can be useful if using two joysticks is difficult or impossible for someone. With this method you use one stick to look/aim/turn, whilst moving forwards, using a switch instead of a second stick. This ‘walk forwards’ option is not available with the Access controller, unless using an additional interface, such as the OneSwitch Walk Box peripheral.

The OneSwitch 19-switch DualSense interface is a way to supplement the features of the Access controller, when there are not enough 3.5 mm ports on an Access controller (four ports), or two paired Access controllers (8 ports) for a particular player.

It can also be used as a ‘standalone’ set-up alongside accessibility switches, when a player may not benefit from the buttons or joysticks on an Access controller, but requires more than eight controller inputs to be accessed using switches and is able to use some of the inputs on a DualSense controller alongside these. If eight or fewer switches are required, they may consider pairing one or two Access controllers with a standard DualSense controller. 

The 19-switch DualSense interface can also be paired with another DualSense controller using the PlayStation 5 console’s ‘Use Assist Controller’ option. This can allow a player to split and use different inputs on the controller with different parts of their body, or play alongside a second player to control one player in-game.
