Pushbutton switches have been a major component of electrical engineering since 1845. This includes the 37FMA1-BEW1N application field and working principle. It is a momentary pushbutton switch which was designed as a reed switch, but with a replaceable plunger. Its primary application is for signaling, controlling, security alarms and monitoring devices ^[1]. It is one of the best solutions for industrial applications.

The 37FMA1-BEW1N is a magnetically operated reed pushbutton switch with a patented design. It is designed to be resistant to holding current, shocks and vibration. It also has a longer life. With a rated current of 30 A, the switching contacts guarantee a high reliability and security. The contact gap is set to 0.5 mm, and the contact gap width is adjustable from 0.2 to 1 mm. It provides a reliable switching capability at voltages up to 250 V AC/22 V DC. It also meets UL, CUL, and IP ratings ^[2].

When the plunger is pressed down, an internal magnet creates an attractive force that pulls the contacts together. This causes an electric current to flow through the circuit, which activates the device. When the plunger is released, the magnetic force dissipates, and the contacts break the circuit. This switching action makes it an ideal switch for industrial, commercial and home alarm systems.

The 37FMA1-BEW1N is a versatile switch. It is available in two different versions, the standard and the flush. The standard version is designed for use in security applications, as it allows for easy access to the switch and can be flush mounted. The flush version is designed for surface mounting and provides protection against the elements.

The 37FMA1-BEW1N is a reliable and durable switch. It conforms to UL and CUL requirements, and is rated for up to 3 A at 250 V AC/22 V DC. It is also rated IP66 for dustproof and waterproof operation up to +85℃. Additionally, it is available in a variety of colors, as well as stainless steel or gold plated housings for added corrosion resistance^[3].

In conclusion, the 37FMA1-BEW1N is a versatile and reliable switch. It is designed for industrial, commercial and home alarm systems. With its high current rating and dustproof and waterproof rating, it is ideal for a wide range of applications.
