Snap action switches are among the most widely used of all control products and are generally known by several names, such as limit switches, toggle switches, micro switches and miniature switches. They are an essential part of many mechanical and electrical systems, providing reliable means of sensing the location, velocity or acceleration of a moving part, process or machine part. The 914CE19-9A is a reliable and robust snap action switch and this article will provide an overview of its application fields, physical features, and working principles.

Application Field

The 914CE19-9A snap action switch offers a wide range of application, including:

• Machine tools
• Robotics
• Industrial Automation
• Sensors
• Home Automation

It is specifically designed to tolerate demanding environments, including high shock and vibration, making it ideal for a variety of industrial applications. This switch is also UL, CUL and DIN approved, making it suitable for any general purpose or specialty equipment.

Physical Features

The 914CE19-9A snap action switch is built with a robust die-cast metal construction, complete with a waterproof IP67 rating. The switch has a standard 4-pin connection, while it is also equipped with a 9.5A, 300V rated contact system. This ensures the switch works properly even when exposed to high temperatures or harsh conditions. The dimensions of the switch are 7.62mm x 5.08mm, with an operating temperature range of -45C to +125C. The switch also features a long life expectancy of up to 1 million cycles.

Working Principle

A snap action switch is a type of switch that functions by means of a spring-loaded plunger or contactor. The switch uses mechanical force to move a contact “on” or “off” from one position to another. The switch operates through contact sparking, whereby when a certain current passes through the switch the contacts spark and move to the opposite position. This works in both the on and off states and is what gives the switch its “snap action” characteristic.

The 914CE19-9A snap action switch has one normally open contact and one normally closed contact. When pressurised, the spring-loaded actuator contacts move to the on position and the switch’s output is held in the on position until the pressure is released. This ensures reliable switching action, making the switch suitable for precision applications.

Conclusion

The 914CE19-9A snap action switch is a reliable and robust solution for sensing the location, velocity or acceleration of a moving part, process or machine part. It is specifically suited for demanding environments and has a long life expectancy. With this switch, users can expect a dependable performance in any mechanical or electrical system.
