Toggle Switches

The M2015SA2A40 is a popular toggle switch among electronics hobbyists. It is a single-pole, double-throw (SPDT) switch that supports up to 5 Amps of continuous current. It has high reliable contact throughout its life due to its construction, making it a great choice for circuits that have to cycle many times, such as sound systems, motors and automotive applications.

Application Field

The M2015SA2A40 is a great choice for hobbyists, professionals and general everyday users. It can be used for a wide range of applications, including electronics project switching, signal switching, relay control, reversing motor polarity, motor speed control, and circuit selection. It can also be used to select between different audio and video signals.

The M2015SA2A40 is especially useful for automotive applications. It can be used for controlling the power to electric devices, reversing motor polarity, controlling AC power, and for general circuit protection. It is also often used as a reverse polarity switch in cars, due to its ability to handle high currents and its long-lasting high reliable contact.

Working Principle

The M2015SA2A40 toggle switch has three terminals; the common (C), the normally closed (NC) and the normally open (NO). When the switch is in its off position, the common (C) and normally closed (NC) terminals are connected, allowing current to flow between them. When the switch is switched on, the common (C) and normally open (NO) terminals become connected and current flows between them, while the NC terminal is disconnected.

The switch can also be used to select between multiple devices/circuits. When the switch is in its Off position, the Common (C) and Normally Closed (NC) terminals are connected and the Normally Open (NO) is disconnected. When the switch is switched On, the Common (C) and Normally Open (NO) terminals are connected and the NC is disconnected. This allows the user to select which device/circuit is active.

The M2015SA2A40 toggle switch is a rugged switch well-suited for applications where high reliability and long-lasting performance are required. It is most often used for switching between different audio and video signals, controlling the power to electric devices, reversing motor polarity, controlling AC power and general circuit protection. Its simple design and convenient switching operation make it a popular choice among hobbyists and professionals alike.
