MSPF101B

Pushbutton Switches

The MSPF101B is a popular single-pole, single-throw (SPST) pushbutton switch. It is widely used in a variety of applications including industrial, marine, and commercial applications. This type of switch is typically used to manually control the operation of a machine or to provide a momentary action which can be used to turn something on or off or trigger certain functions. The switch is usually actuated by pressing and releasing a button, known as the actuator, or by pushing a lever, known as the lever arm, in some applications.

Application Fields

MSPF101B has a wide range of application fields. Most commonly, it is used for industrial and commercial applications, such as in elevators and escalators, printing presses, amusement rides, counter-top displays and store windows. Other applications include medical laboratory equipment, industrial and medical alarm systems, and instrument control systems. It is also used in the marine industry for on-board components and elsewhere where a reliable switch is required.

Working Principle

The MSPF101B works using a simple, yet reliable, system of mechanical components. At its core, it uses a coil spring and a metal ball that is held in place by the spring-loaded pin. When the switch is pressed, the metal ball is pushed down, breaking the electrical contact and completing the circuit. When the switch is released, the pin and the spring move the metal ball back up, restoring the electrical connection, thus allowing the electrical current to pass again.

An additional feature of this type of switch is the lever arm that allows the actuator, or button, to be moved. This lever arm allows the user to keep their finger on the switch and still make a contact, thus providing a momentary action when the switch is held down.

MSPF101B is a reliable, cost-effective switch choice for many applications and has been a go-to switch for decades. It is available in a variety of configurations and materials, making it customizable for different settings. The reliability and low cost of this switch make it a popular choice for a variety of applications.
