The Palmer PF2SW is a variable dual footswitch for all devices with a footswitch port. It is suitable for channel switching of amplifiers, to turn on and off built-in and external effects, and can independently control two devices; bright LEDs indicate the switching status. The two circuits of the PF2SW can be adjusted individually to the respective function of the connected devices. To do this, the sliding controller chooses between contact closure and electronic impulse as well as open or closed position of the relay, a further controller selects one of the two footswitches as master for simultaneous switching of both circuits. In most applications, the PF2SW can be connected using conventional 6.35 mm jack cables.
