Pushbutton Switches

A pushbutton switch, also known as a momentary switch or non-latching switch, is a type of switch which is only active for as long as it is being pressed, and is used to control electrical devices and connections. One of the most commonly used types of pushbutton switch is the 38BT-O-H-4-N, which is a single-pole momentary switch, meaning it is only active for as long as it is held down. Here, we’ll examine the application field and working principle of the 38BT-O-H-4-N.

Application Field

The 38BT-O-H-4-N pushbutton switch is commonly used in a variety of commercial, residential and industrial applications. In residential settings, the 38BT-O-H-4-N is often used to control lighting fixtures, appliances, fans, pumps and other electrical devices which require a momentary switch. In addition, the 38BT-O-H-4-N is widely used in commercial and industrial installations to control motors, pumps, solenoids, and other high-power electrical devices.

Working Principle

The 38BT-O-H-4-N pushbutton switch operates using a single-pole single-throw (SPST) mechanical momentary switch which is activated when the button is pressed and released when it is released. The momentary switch is connected to two electrical contacts, with one acting as a "common" terminal and the other acting as an "operating" terminal. When the button is pressed, the common terminal connects to the operating terminal, thus allowing current to pass through.

When the button is released, the common terminal is disconnected from the operating terminal, thus preventing current from passing. The 38BT-O-H-4-N can be used in conjunction with other accessories, such as LEDs or sounders, in order to provide helpful visual and audible feedback when the button is pressed.

Conclusion

The 38BT-O-H-4-N pushbutton switch is a single-pole momentary switch which is typically used in residential, commercial and industrial applications. The 38BT-O-H-4-N operates using an SPST mechanical switch which is connected to two electrical contacts. When the button is pressed, the contacts connect, thus allowing current to pass; when the button is released, the contacts disconnect and the current is cut off. The 38BT-O-H-4-N is a helpful and versatile pushbutton switch which can be used to control a variety of electrical devices.
