VB-4251

Snap action, limit switches are ubiquitous in industry, and the VB-4251 is no different. It is a single pole, double throw switch with a unique construction and wide range of applications.

The VB-4251 switch is constructed of a stainless steel body with two brass contacts. The switch is actuated by a plunger connected to a lever arm that is spring-loaded. Under the mechanism is a plastic cover to protect the contacts from dust or moisture.

The VB-4251 switch is used in a variety of applications, from general industrial controls to medical instruments. Its versatility comes from its ability to be used with either AC or DC voltages, as well as its ability to act as a normally open or normally closed switch. It is also used in high current applications, as the contact resistance is very low.

The working principle of the VB-4251 switch is relatively simple. When the plunger is pressed by a lever arm, it releases the leaf spring and allows the contacts to touch, thus closing the circuit. When the lever arm is released, the plunger moves back up and releases the contacts. This opens the circuit, which re-enacts the original position.

Overall, the VB-4251 switch is a reliable and durable option for controlling current. Its ease of use, wide range of applications, and low contact resistance make it a great choice for industry-wide usage.
