83274021

Snap Action, Limit Switches

The 83274021 is a snap action limit switch designed for industrial applications. It is used to detect the presence of an object, such as the end of a conveyor belt, the end of a machine part, or the opening or closing of a door. It can also be used as part of a safety system, such as a limit switch on an automated production line. The 83274021 is a single pole, double throw (SPDT) switch, meaning that it has two switched states – one when the object is present and one when it is not present. The switch is rated up to 15A, 250VAC.

The switch itself consists of a snap action spring, a movable contact, and two fixed contacts. When the object is present, the contact is pushed closed, and the two fixed contacts are electrically connected. When the object is not present, the contact is released and the contacts are no longer connected. This can be used to control a circuit by turning it on and off, or to detect the presence of an object.

The operating principal of the 83274021 switch is based on a spring-mounted contact that is pushed closed when the object is sensed. The spring tension keeps the contact closed, until the object is removed and the spring can return the contacts to an open state. This allows the switch to be activated quickly, without the need for complex wiring or sensing mechanisms.

The 83274021 limit switch is designed for industrial applications, and is suitable for use in wet and dusty environments. It is made of a rugged thermoplastic housing, and has a long operational life of up to 10 million cycles. The switch has a wide operating temperature range, from -20°C to +80°C, making it suitable for use in many different applications.

Overall, the 83274021 switch is a reliable and durable limit switch, ideal for industrial applications where quick, accurate switching is required.
