Snap action, limit switches are essential components in automatic control systems. They are used to detect the position of mechanical components, to provide reliable control points, and to prevent dangerous conditions, such as over temperature and over pressure. This article is about the 83261017 snap action, limit switches and the working principle behind them.

The 83261017 snap action switch consists of a base plate, an actuator deployed on the plate, and contacts employing spring-loaded arms. When an object strikes the actuator, snapping action is provided and the contacts are opened or closed depending on the desired action. This action also provides protection from dust, water, and other elements allowing the switch to work in harsh environments. Additionally, the switch operates in a temperature range from -40°F to 120°F.

When operating this switch, the actuator and contacts are pressed onto the base plate. The contacts are pushed inward against two metal springs. In the rest position, an electric current starts from the common pole of the switch and flows through the normally open contact to the normally closed contact through the metal springs. When an external force or pressure is applied to the actuator, the metal springs compress and the contacts separate, causing a circuit interruption.

The design of this switch relies heavily on the application and is customizable with tightly enclosed contacts, spacers and brackets. It is designed to eliminate the need for costly and complex housings to protect it from hostile environment conditions. Furthermore, since the switch is constructed entirely of non-corrosive materials, it provides extended service life and requires minimal maintenance.

In addition to the snap action, limit switches, there are also safety interlock switches, rotary switches, and foot switches. These types of switches provide the same kind of action as the snap action switches, but rely on a different type of movement or actuation for operation. Safety interlock switches are used to prevent a machine from starting unless the guard doors are closed, and features two interlocked contact pairs that can only be opened when the guard doors are closed. Rotary switches are used to control the amount of voltage or current in a system and use a rotating mechanism to activate or deactivate a circuit. Foot switches are used to activate or deactivate a circuit using your feet, allowing for hands-free operation.

The snap action, limit switches are ideal for applications in which simple, reliable and wide temperature range switches are required. It is also suitable for use in harsh environments, like in factories and laboratories. When installed and used properly, they provide reliable and effective control of a system.
