The MSP103B is a type of pushbutton switch, which has a range of uses in a variety of applications. It is a miniature momentary contact switch, with a black shot actuator, and is made of a highly durable polyamide material. It is designed to be mounted on a 10 mm diameter panel cutout, and needs either a single or double-pole contact configuration for operation. The MSP103B is most commonly used for controlling or monitoring electrical circuits, as a garage door opener, and as a plunger reset switch in fire alarm systems.

Unlike other types of switches, a pushbutton switch such as the MSP103B relies on physical pressure to activate, rather than electrical signals. When the button is pushed, the internal contact mechanism creates an electrical connection that allows current to flow through the circuit. This connection can only be made when the external buttons are depressed, allowing for greater control of electrical devices in applications where power is required only briefly.

To understand the working principle of the MSP103B, it is important to break down each component of the device and understand how they function together. The switch has four main parts; the mounting bracket, contact mechanism, actuator button and cam plate. The mounting bracket is what houses and secures the switching mechanism and the actuator button, and the contact mechanism is the part responsible for controlling the flow of electricity.

The actuator button is the part of the switch that is actuated when the switch is pressed. When the button is depressed, it moves the cam plate, which then compresses the silver contact spring. This action causes the silver contact spring to switch from open to closed and thus creates an electrical connection. The opposite effect happens when the button is released, and the silver contact spring returns back to its original open position. The MSP103B also comes with a reset button which, when pressed, allows the contact to return to its open position regardless of whether the button is pressed or not.

The MSP103B can be used in a variety of applications including motor and equipment control, lighting and heating systems, and alarms. In motor control applications, the MSP103B can be used to control the motor movement on/off and to control the speed of the motor. In lighting and heating systems, the MSP103B can be used to control the ON/OFF of lights and other heating devices. In alarm applications, the MSP103B can be used to control the arming and disarming of the alarm system or to reset the alarm in case of malfunction.

The MSP103B is a highly reliable switch, that has a variety of applications and uses. By understanding its components and working principle, it is easy to see why the MSP103B is an effective and practical solution for a variety of applications. As long as the device is correctly installed and correctly used, it can provide a reliable and consistent source of power for a variety of applications.
