Item # TS-20, TouchStart Palm Button, Includes Mounting Jam Nut and Gasket, 24 VDC



Capacitive Palm Button
  • No physical pressure required to actuate switch—reduces the likelihood of wrist injury caused by repetitive motion.
  • Excellent sensitivity—sensor is designed to operate even if operator is wearing gloves.
  • RFI Immunity—special circuitry inhibits output in the presence of RFI that would otherwise cause false triggering of output.
  • AC version is UL Recognized—meets the applicable requirements in the proposed first edition of UL 491.
  • Saves time and money.
    – Easy mounting in a single hole.
    – Wiring is simplified because terminals are clearly identified and easily accessible.
    – No special power supplies are required because switch is available in either 120 VAC or 24 VDC versions.
