V7-1S17D8-201

Snap action switches, also known as limit switches, are electromechanical devices that quickly respond to changes in their environment. The V7-1S17D8-201 is a type of snap action switch designed to provide accurate, reliable positional detection and switching. It is used in a variety of applications, such as safety switches, machinery automation and process control.

The V7-1S17D8-201 is a miniature, robust and economical switch with a snap action lever that can be actuated with low actuation force. It is energized with a single-pole/double-throw (SPDT) contact that can be used to switch either AC or DC current. The switch housing is made of a durable polybutylene terephthalate plastic and its bottom case is soldered to a PC board for reliable long-term performance.

The V7-1S17D8-201 switch comes with an adjustable armature and can be used in a wide range of applications. Its adjustable design allows for easily set actuator stop points, allowing for more precise switch settings depending on the application. Moreover, the switch can be reversed to discriminate between normal-open or normally-closed operation.

The switching elements of the V7-1S17D8-201 are constructed using stainless steel for superior corrosion resistance and long-term durability. The contact points are flame-retardant, non-corrosive and offer superior life expectancy. The contact design is optimized for maximum reliability and minimal electrical arcing. This switch is suitable for industrial applications and has been designed to operate in tough environmental conditions.

The working principle of V7-1S17D8-201 is similar to other snap action switches. It operates when an external force is applied to the actuator which then compresses an internal spring mechanism, eventually overcoming the force required to move a contact between its two different switch positions. The contact is then held in its respective position until an opposite force is applied, causing the mechanism to rebound and the contact to move back to its original position.

The V7-1S17D8-201 is widely used in many different types of process control, industrial automation, safety switch, and other electrical applications. It is ideal for applications where a reliable and accurate switch is needed to detect and actuate on a given force or position. The switch is UL approved and has been tested for its accuracy and durability.
