The Square Series includes Models 11, 21, 31, 35, and 81. These switches feature a rugged 38mm or 25mm square housing, designed for hazardous and high-vibration environments. Their hermetically sealed contacts, snap-action response, and non-contact sensing deliver dependable performance in applications ranging from chemical processing to energy and OEM installations.


  • Model 11 – Classic design with SPDT contact, brass or stainless steel housing
  • Model 21 – Compact version of Model 11
  • Model 31 – End-sensing with compact stainless housing for hazardous zones
  • Model 35 – Intrinsically safe for high/low load environments
  • Model 81 – Offers DPDT contact configuration for explosion-proof needs

Round Series – Maintenance-Free, Sealed Design

The Round Series, including Models 71–77, 7G, 7H, 7LG, and 7LR, is engineered with a sealed stainless steel enclosure and no external moving parts—ideal for wet, corrosive, or extreme conditions. These switches are frequently used in control valve, power generation, and marine environments.


  • Models 71–77 – SPDT 4A/3A/0.5A contacts with end-sensing
  • Models 7G / 7H – Offer hermetic seals and optional DPDT contacts
  • Models 7LG / 7LR – Integrated BriteLite™ LEDs for visual status indication (Green/Red)
