Single Pole Single Throw (SPST) Momentary Push Button switch is a type of switch that is designed to control the flow of electrical current in a single circuit. It is a simple and commonly used switch that is widely used in the electronic industry due to its simplicity, durability and ease of use. The switch is widely used in various applications such as audio-visual equipment, home automation systems, electronic toys, computer peripherals, and medical devices, among others. In this article, we will discuss the Single Pole Single Throw (SPST) Momentary Push Button switch in detail and its applications.
A momentary round push button switch with an LED indicator is a versatile and practical component widely used in various electrical and electronic systems. Here's an in - depth look at its features, functionality, and applications.
This type of switch typically has a circular shape, which offers an ergonomic design for easy pressing. The switch body is usually made of durable materials such as plastic or metal, providing protection for the internal components and ensuring mechanical strength. Inside, it consists of a button mechanism, electrical contacts, and an LED module. The LED is often positioned at the center or around the edge of the button, allowing its light to be clearly visible when activated.
Switch Operation: As a momentary switch, it functions on a “press - to - connect, release - to - disconnect” principle. When pressure is applied to the round button, internal mechanical components move, closing the electrical contacts and completing the circuit that the switch is a part of. Once the pressure is removed, the contacts open, and the circuit is broken.
LED Indicator Function: The LED indicator is integrated into the switch in a way that it can be powered independently or in relation to the switch's state. In some cases, the LED lights up whenever the switch is pressed and the main circuit is closed, providing visual confirmation that the action has been executed. In other designs, the LED can be set to remain on continuously, indicating that the device or system the switch controls is powered up, or it can flash to signal specific events or error conditions.
