By the FINA rules it is necessary for swimming to have additional to the touch pads push button(s) for each lane. Most events need only one per lane, but for some big events the rules require three push buttons per lane. The ALGE TM-SWIM allows connecting for each lane up to 3 push buttons.

The ragged push button 023-02 has a big and water proof button. The plastic case is completely sealed, so it does not matter if it falls into the water. The cable length is two meter and it has banana plugs to connect it.
