Snap Action, Limit Switches

The VB-6221 is an electric snap action, limit switch from Crouzet. It is an excellent choice for automation applications in complex and harsh environments. This device is designed for applications that require reliable operation, minimal maintenance, and consistent performance in extreme temperatures. The VB-6221 is also compatible with major brands of programmable logic controllers (PLCs) and other automation components.

Application Field

The VB-6221 is applicable in a wide range of industries. Its highlights include:

• Rugged construction Ideal for harsh conditions such as extreme pressure, extreme temperatures, and vibration
• Low-level control interface Compatible with major brands of PLCs and other automation components
• High power capacity Resistant to heat and high power applications
• Long service life Designed for an extended service life
• Wide range of mounting options Mounting hardware is included

The VB-6221 is an ideal choice for controlling the operation of pumps and motors, controlling fans, detecting open/closed states of doors or gates, and switching on/off lights and alarms.

Working Principle

The VB-6221 snap action, limit switch uses a mechanical overlay and a plunger to open or close a momentary contact switch. When the plunger is pushed, the contact switch is activated, allowing an electrical current to flow through the switch and initiate an action. Conversely, when the plunger is released, the contact switch is deactivated, thus stopping the flow of electrical current.

The VB-6221 features two distinct modes. In the vertical mode, the plunger is normally in the off (down) position. When the plunger is pressed down, the switch is activated. This mode is useful for detecting the opening/closing of a door, gate, or other mechanism. In the horizontal mode, the plunger is normally in the on (up) position. When the plunger is pushed to the off (down) position, the switch is activated.

The VB-6221 is designed for priority applications. Priority applications are those that require reliable operation and minimal maintenance. This device offers long service life, even in extreme temperatures, and is resistant to heat, pressure, and vibration. It also features a wide range of mounting options, ensuring a versatile fitment.
