This optional foot switch accessory for the HDT-48-00PN pneumatic crimper allows the user to operate the crimp tool while keeping both of their hands free to provide a quick and precise crimp. Simply connect the foot switch to the HDT-48-00PN and you are ready to control your crimps with a press of your foot. The foot switch activates the compressed air used to activate the crimper which does not require electrical connection. With both hands free you can create uniform strong crimps much easier.
