Pushbutton switches are devices used to control essential electrical signals. The 38BC-4-V-3-S pushbutton switch is a popular choice for commercial and industrial applications due to its reliable performance and affordability. In this article, we will discuss the application field and working principle of the 38BC-4-V-3-S pushbutton switch.

Application Field

The 38BC-4-V-3-S pushbutton switch is ideally suited to industrial control applications. It is used in many applications throughout the industry, including control of process equipment, manufacturing machines, motor starters and HVAC systems. The 38BC-4-V-3-S is also common in commercial settings, such as elevator call buttons and pedestrian crossing buttons.

The switch is designed to be used in both indoor and outdoor environments, being capable of withstanding temperatures down to -40°C. It is also resistant to dust, water and oil, making it perfect for places where harsh conditions are present.

The 38BC-4-V-3-S switch is also suitable for use in hazardous locations, making it the perfect choice for environments where there is the potential for the presence of flammable gases and vapours. The switch has both ATEX and IECEx approval.

Working Principle

The 38BC-4-V-3-S pushbutton switch is an illuminated type, meaning it is fitted with a light that lights up when the button is pressed. When the button is pressed, it causes the internal contacts to make a connection, which creates a circuit and sends an electrical signal. The switch also incorporates a protective metal sleeve which reduces the possibility of accidental shorts.

The 38BC-4-V-3-S switch has adjustable actuating force, meaning that the user can adjust the switch to require more or less pressure to be applied before the contacts close. This allows for greater control over how quickly the switch actuates. Additionally, the switch is available with different switching elements, offering both Normally Closed and Change-over contacts.

The 38BC-4-V-3-S switch also has a highly visible LED indicator, which can be set to one of three colours - red, yellow or green. This can be used as a visual indication when the switch is activated, as well as providing protection against incorrect wiring.

Finally, the 38BC-4-V-3-S switch is designed to be low-maintenance, with a long-life design that requires no adjustment during normal operation.

The 38BC-4-V-3-S pushbutton switch is a reliable, durable and cost effective choice for industrial and commercial applications. Its tough construction and adjustable actuating force make it ideal for applications such as process control, emergency stop and industrial machinery. Its adjustable LED indicator and long-life design also make it a great choice for any application that requires an illuminated switch.
