BlueSwitch accepts up to three input-switches (3.5mm mono jacks) and converts them into Bluetooth switches for accessing iOS, Apple OS X, Windows, and Android devices. Additionally BlueSwitch lets you use these same input switches to connect to up to three Bluetooth devices! Now you can use a single switch to control your iPad, smartphone, and computer -- and seamlessly switch among them. In addition, BlueSwitch has two relay outputs (3.5mm mono plugs) allowing the same input switches to signal or control other devices such as battery-operated toys or nurse call switches. BlueSwitch supports Bluetooth auto-reconnect when powering up. BlueSwitch is 3.1" x 3.7" x 1" thick and weighs 4.5 ounces.

BlueSwitch is highly configurable, making it possible to optimize BlueSwitch for the abilities and limitations of the person using it. DIP switches on BlueSwitch's side panel provide the standard options most people will need. These options include selecting the keys that will be sent via Bluetooth ('space' and 'enter', or '1' and '3'), and choosing whether user input-switches 1 and 2 cause Bluetooth data to be sent upon switch press or release. In custom mode many more options are available.

If the default options do not work for you, the custom mode can be configured using BlueSwitch's Android app. The BlueSwitch app is free and available in the Google Play store

The battery inside of BlueSwitch will last all day. Charging time is four hours. The battery level is indicated by the four green LEDs surrounded by the battery symbol, or more precisely using the free Android app.

BlueSwitch has three input-switch connections (3.5mm mono jacks). Input-switch 1 and/or 2 (SW 1 and SW 2 on the side panel) are designed to perform switch access on Bluetooth connected devices. Input-switch 3 (SW 3) is a dedicated to cycle through connected devices and select which device your input switches (SW 1 and SW 2) will control. When none of your Bluetooth devices are selected (as indicated by the lack of an amber LED next to any device number on the front panel) the switches connected to SW1 and SW 2 control the output relays (described below). This enables the user to control switch-enabled devices that do not support Bluetooth. Switch 1 can also be configured to cycle through connected devices by a long switch press (time threshold settable in our free BlueSwitch Android app).

BlueSwitch has two relay outputs (3.5mm mono jacks) which can be activated using input-switches 1 and 2. This allows the input switches to be used for hardwired switch access, such as a a switch-activated TV remote control or nurse call switch. The relay outputs are selected when none of the Bluetooth devices are being accessed.

BlueSwitch supports simultaneous Bluetooth connections to three devices with auto-reconnect on power-up. When a device connects to BlueSwitch, the LED next to the device number will turn green. When sequencing through the devices, the device selected for control will have an amber LED, instead of green. If none of the device LEDs are amber, the relays are active. The four DIP switches on the right side of BlueSwitch enable to user to select among three standard operating modes and one custom mode. The on/off functions of each switch are defined below:

  1. When DIP switch 1 is 'off', BlueSwitch is in standard mode, which enables the options controlled by the next three DIP switches. When DIP switch 1 is 'on' BlueSwitch is in custom mode, which disables the functionality of DIP switches 2, 3, and 4 and instead uses the switch settings from our free BlueSwitch Android app.
  2. When DIP switch 2 is 'off', BlueSwitch sends the numbers '1' and '3' via Bluetooth. When DIP switch 2 is 'on', BlueSwitch sends 'space' and 'enter' via Bluetooth. These are the common pairs of characters used for Bluetooth switch access. 
  3. When DIP switch 3 is 'off', the switch activation is sent via Bluetooth when user switch 1 is pressed. When DIP switch 3 is 'on', the switch activation is sent when user switch 1 is released.
  4. When DIP switch 4 is 'off', the switch activation is sent via Bluetooth when user switch 2 is pressed. When DIP switch 4 is 'on', the switch activation is sent when user switch 2 is released.

The DIP switches on BlueSwitch's side panel provide the standard options most people need. In all modes, input-switch 3 selects which paired Bluetooth device is controlled by BlueSwitch. Activating input-switch 3 for more than 3 seconds causes BlueSwitch to auto-reconnect to paired Bluetooth devices (this time is adjustable in custom mode). Releasing input-switch 3 before this time selects the next Bluetooth device to be controlled. All of this is complicated to write, but pretty easy to use. Call us if you would like help figuring this out. :-)

In the custom mode the functions of input-switches 1 and 2 are highly configurable. BlueSwitch's custom mode comes preprogrammed to enable input-switch 1 to send the Bluetooth keys '1' on a short switch closure (less than 1.5 seconds), '3' on a long switch closure (1.5 - 3.0 seconds), and to start scanning paired devices on a switch closure that is held for more than 3 seconds. Input-switch 2 comes preprogrammed to send 'space' on a short closure and 'enter' on a long closure. You cannot scan ports using input-switch 2. The preconfigured custom mode therefore enables single-switch users to control up to three Bluetooth devices, plus one relay output, using only input-switch 1!

Customizing BlueSwitch is accomplished using our free Android app. The BlueSwitch app enables the following parameters for input-switches to be set:

  • Tell BlueSwitch to differentiate between short and long input-switch presses for input switches 1 and/or 2.
  • Tell BlueSwitch the press duration for a long switch press for input switches 1 and/or 2.
  • Tell BlueSwitch to send Bluetooth commands on switch press or release for input switches 1 and/or 2.
  • Tell BlueSwitch to wait for an acceptance time before sending a Bluetooth command for input-switches 1 and/or 2. If the acceptance time is not met, nothing is sent. This is helpful for people who tend to accidentally reactivate their switch when pressing or releasing.
  • Tell BlueSwitch the time that input switch 1 and/or 3 must be activated in order to enter the Bluetooth device selection mode.
  • Tell BlueSwitch which HID character to send on switch activation for input switch 1 and/or 2. Options include characters A-Z, F1-F12, 0-9, Space, and Enter. 
  • Tell BlueSwitch to enable/disable the feedback beeper which indicates when an input switch has reached a long press threshold.

The above settings should make it possible for nearly any switch-user to control multiple Bluetooth devices. If you would like help configuring your BlueSwitch or have questions, just call us. We are more than happy to help!

The free BlueSwitch app is available in the Google Play store.

BlueSwitch enables a person who uses a switch (or two or three switches!) to control up to three smart devices -- as well as one hardwired switch-access device, such as a TV remote control or nurse call. For example, a person controlling a single-switch can control their Android smartphone, check Facebook on their iPad, complete their homework on their Windows computer, and activate a nurse call. One switch can control all of these devices!

Of course, some people do better with two switches. BlueSwitch also lets you use two switches for controlling your smart devices -- and to switch between them. Finally, if you can manage three switches, you can use all three for controlling your devices.

BlueSwitch gives switch users access to the same technology that everyone else enjoys!
