The EpiShear Footswitch makes it more convenient to deliver short pulses when using the unit in manual mode, or when performing experiments that require you to hold the converter/probe or otherwise have use of your hands. The footswitch is plugged into the back of the EpiShear and placed on the floor so that the sonicator can be pulsed ON and OFF using your foot, instead of having to push the PULSE button on the sonicator repeatedly.
