Pushbutton Switches are widely used in all kinds of electronic and electrical circuits, from industrial controls and communication systems to domestic appliances. The 1222MA is a Micro-Pushbutton Switch with a unique design that optimises performance and minimises size.

Background

The 1222MA pushbutton switch was designed in 1989 by Taigur Corporation in collaboration with experts from the appliance and control industry. The design brief was to create a small, low-cost micro switch to meet the ever-growing demand for space-saving solutions. The development and design process was completed in early 1990 and the 1222MA was born.

Purpose

The 1222MA is an essential component in modern control and communications engineering. Its primary purpose is to provide a cost-effective, space-saving solution for applications such as medical, transport, telecommunications and industrial air and power controls.

Design

The 1222MA is a 2-pole and 2-position pushbutton switch measuring 16.3mm (length) x 8.3mm (width) x 8.3mm (height). It is designed with a solid copper material, gold plated contacts and an epoxy-sealed ABS switch housing. It has two contacts, a normally open contact and a normally closed contact, referred to as \'NO\' and \'NC\'. It includes a screw-type terminator (with M2.5 thread) for connection to other circuits.

Applications

The 1222MA can be used for a variety of applications where space is limited and a cost-effective solution is desired. It is commonly used for industrial controls, such as motor starters and power switches, as well as for debugging, circuit testing and testing switches in electronic equipment. It is also suitable for use in appliances, such as washing machines and cookers, as well as in telecommunications and data communication systems.

Working Principle

The 1222MA operates by using a simple push-on push-off contact set. When pressure is applied to the switch, the contacts close and an electric current flows through the switch. When pressure is released, the contacts open and the current stops flowing. This allows the 1222MA to be used as a control switch in many different types of devices and systems.

Advantages

The 1222MA has a number of advantages over other types of pushbutton switches. Its small size and low cost make it an attractive option for designers and engineers in the appliance, industrial control and communication industries. Its robust construction and ability to handle high currents make it suitable for demanding conditions. In addition, the screw-type terminator makes it easy to install and helps to ensure reliable connections.

Conclusion

The 1222MA Micro-Pushbutton Switch has been a popular choice for engineers and designers for many years. Its small size, low cost and ease of installation make it a cost-effective and reliable option for a variety of applications. The solid construction, gold plated contacts and epoxy-sealed housing provide a robust and durable switch that can handle high currents and temperatures. Its versatility and reliability make it a great choice for any control and communications engineering project.
