Limit Switch

Range:  Precision and Oil Tight Limit Switches

Bhartia Cutler-Hammer’s limit switches are designed with one aim: to help produce better, produce faster with least downtime. The limit switches are offered as precision limit switches and oil tight limit switches.

◉  Precision Limit Switches:  The precision limit switches are designed for industrial applications. These are small, reliable in operation, boast exceptionally long life and are extremely accurate. The wide variety of switch operating mechanisms coupled with the choice of either single pole (1NO + 1NC) or double pole (2NO + 2NC) changeover contacts permit easy selection and application for many needs. A wide variety of operators are available for use with the basic switch. These operators with mounting variations offer a high degree of versatility.

Types of operators:

  • Push button plunger
  • Top push button pulnger
  • Six inch lever
  • Roller lever


  • Utilization category AC11 and DC11 as per IEC 337-1 and IS 6875
  • Thermal current 15A
  • Insulation voltage 600V (AC)
  • Frequency of operation: 2500 operations per hour
  • Mechanical life: 20 million operations
  • Electrical life: 10 million operations

◉  Oil Tight Limit Switches:  These limit switches are designed to operate in highly contaminated atmospheres and extremely high shock and vibration conditions. Every limit switch off the assembly line passes through rigid tests before being operational in the field.

The “Set Back” head design offers greater structural rigidity. These limit switches are completely oil tight, water tight and dust tight, provide ample space at terminals for easy wiring and the contacts have thermoplastic barriers to prevent short circuit.
