SinglePoleSingleThrow

SinglePoleSingleThrow (SPST) is a type of electrical switch that has one input terminal and one output terminal, with a single pole that can be thrown to either connect or disconnect the input from the output. It is the simplest form of switch, commonly used in various electronic and electrical applications. The SPST switch typically has two positions: one where the input is connected to the output, and another where it is disconnected. This configuration is often used in circuits where a simple on/off function is required, such as in lighting controls, simple alarms, or basic electronic devices. The switch can be manually operated, often by a button or lever, and is widely used due to its simplicity and reliability. SPST switches are available in various forms, including mechanical, solid-state, and relay-based versions, each suited to different applications based on factors like voltage, current, and environmental conditions.
