Pushbutton Switches are a crucial element in electrical and electronic systems. The PN12SHSA03QE is an example of a Pushbutton Switch with the ability to provide reliable and consistent performance in a wide range of applications. A deeper understanding of the features, application field and working principle of this switch can help engineers achieve better results in their designs.

Features of PN12SHSA03QE Pushbutton Switch

The PN12SHSA03QE is a rocker style switch which has a total of two positions. It has a full plastic construction for reliable switching and sealing, and it is coated with a plastic layer which provides protection from dust, water and oil penetration. The switch is rated for 0.6A @ 48VDC and is suitable for use in both low voltage and medium voltage applications. Additionally, it has a number of features which make it suitable for use in a range of different applications.

• The switch is pre-wired which eliminates the need for any complicated wiring.
• The switch has a low-profile design to provide more space for adjacent switch components.
• The switch is UL-listed, suitable for use in hazardous locations.
• The switch has a reliable latching mechanism which prevents accidental movement of the switch.
• The switch has a snap-in mounting which makes it easier to mount and remove from the application.

Application Field of PN12SHSA03QE Pushbutton Switch

The PN12SHSA03QE switch is designed for use in a variety of applications due to its robust construction, low profile design, and UL listing. These applications range from fuel pumps and emergency lighting, to HVAC systems, industrial machinery, and medical equipment. The switch is also suitable for use in hazardous locations and can provide reliable, consistent performance even in harsh environments.

Working Principle of PN12SHSA03QE Pushbutton Switch

The PN12SHSA03QE switch is activated by depressing the protruding rocker, which creates a connection between two electrical contacts. The closure of these contacts then causes a flow of current through the switch and to the connected device. Once the rocker is released, the switch will return to its open position, breaking the connection and stopping the flow of current. This process is known as latching and is essential for reliable and consistent performance of the switch.

The switch also has an external arm which is used to prevent accidental switching by physically obstructing the movement of the rocker. This arm is connected to the switch and moves with it, providing an extra layer of protection against accidental or unwanted movement of the rocker.

In addition to latching, the switch also has a spring-loaded plunger which helps to keep the switch in the desired position. This feature helps to reduce wear and tear on the internal parts of the switch, resulting in a longer life span.

Overall, the PN12SHSA03QE Pushbutton Switch is a reliable and versatile switch which can provide reliable performance and reliable switching in a wide range of applications. Its robust construction, low-profile design, and UL listing make it suitable for use in hazardous locations and it is suitable for use in a range of different applications.
