Pushbutton switches are mechanisms that can be used to mechanically control electrical circuits. The 38BT-4-H-4-N is a four-pole, double-throw pushbutton switch that is designed to operate in several different applications. This switch is incredibly durable, utilizing a special AC rating for operation. It is UL and CSA rated as well as being TUV or VDE approved.

Applications

The 38BT-4-H-4-N has been used in a multitude of different industries and applications due to its durability and its AC limitation. Some of the applications that this switch has been used in include the following:

• HVAC control systems
• Motorsport automobiles
• Mining Process Control
• Beauty salons
• Industrial controllers
• Hydraulic systems
• CNC machines

This switch has been designed to fit in places where space is limited and can fit into industrial level systems. Its four-pole design allows for an extensive range of electrical configurations allowing for precise feedback for many applications.

Construction

The 38BT-4-H-4-N switch is designed to be both robust and reliable. It is constructed from a high impact and heat resistant plastic body and is rated to serve in temperatures as low as -5°C. The plastic body is accompanied by a silver plated brass contact block that is able to withstand up to 10A of current. The front panel is equipped with a dielectric grade elastomeric and silicone rubber face, which helps keep the switch sealed in areas with high humidity.

Working Principle

The 38BT-4-H-4-N switch utilizes a three-position mechanism, with one pole being a Momentary and the other three being On/Off A and B positions, as well as on/off ‘X’ position. The momentary pole is designed to switch off automatically once the button is released, thus switching off all connections, and then switching them back on when further depressed. The A and B poles are designed to allow for two different control voltages or duties, and the ‘X\' pole offers On/Off switching with a latching type arrangement.

Conclusion

Overall, the 38BT-4-H-4-N is a four-pole, double-throw pushbutton switch that has been designed for a variety of different applications, such as HVAC control systems, motorsport automobiles, mining process control, and more. It is constructed from a high impact and heat resistant plastic body and is equipped with a dielectric grade elastomeric and silicone rubber face for increased durability. Finally, the 38BT-4-H-4-N switch utilizes a three-position mechanism, with one pole being a momentary and the other three being on/off A and B positions as well as on/off ‘X’ position.
