Built to last in the most demanding plant conditions
The original “leverless limit switches,” 10, 20, 30, and 80 Series GO Switches are the ideal replacements for traditional mechanical limit switches. Their sealed contacts, rugged enclosures, no-touch sensing, and snap action response make these switches the ultimate problem solvers for troublesome limit switch applications.


 Square GO Switches

  • Model 11 GO Switch
    The original leverless limit switch, the GO Switch Model 11 features sealed gold flashed contacts, no-touch sensing and snap action response in a square switch design.
  • Model 21 GO Switch
    The Model 21 GO Switch features the same features as the Model 11 in a smaller design: 38MM square x 97mm tall. As with all GO Switches, it can be wired A/C or D/C, N/O or N/C, consumes no power to operate, and has no current leakage or voltage drop.
  • Model 31 GO Switch
    The GO Switch Model 31 offers end sensing in a compact stainless steel enclosure that withstands physical abuse, moisture and corrosives. It features SPDT 6A contacts and is suitable for Zone 0, 1, or 2 (Div 1 & 2) explosion proof applications.
  • Model 35: The GO Switch Inside
    The GO Switch Model 35 leverless limit switch has set the standard for reliable performance in valve position monitors. Now available in copper SPDT and stainless steel DPDT models.
  • Model 81 GO Switch
    The GO Switch Model 81 offers end sensing and an optional Double Pole Double Throw (DPDT) contact arrangement. It can be wired AC or DC, N/O or N/C.
