Rotary Switches

A rotary switch is an electrical switch in which the contacts are changed when a rotatable contact arm is turned. It has multiple contact positions, one for each connection. When the arm is turned to the right position, the corresponding connection is made.

44M45-01-1-08S

The 44M45-01-1-08S is a rotary switch specifically designed with a combination of latching and momentary switching capabilities. It consists of four positions - off, on, new-momentary and latching-momentary. It is isolated with dielectric strength of up to 1500 Vrms and has a mechanical life of 25,000 operations. It features two main output terminals - one for latching-momentary and one for new-momentary. It also features LED indicators for each position.

Application Field

The 44M45-01-1-08S rotary switch is commonly used in a variety of applications, from industrial equipment to home appliances and HVAC systems. It is especially useful in automotive and other transportation-related applications, including cars, trucks, buses, and trains, where its versatility provides multiple switching functions in a single unit. Additionally, it is widely used in medical equipment and home entertainment systems, as it can be installed in tight spaces.

Working Principle

When the switch arm is in the off position, both output terminals are open. When the arm is moved to the on position, both terminals are closed, providing power to the circuit. When the arm is moved to the new-momentary position, the corresponding connection is made and held for as long as the arm is held in that position. In the latching-momentary position, the connection is made and latched until the arm is returned to the off position, at which point it is disengaged.

Conclusion

The 44M45-01-1-08S rotary switch is a highly versatile device that provides multiple switching functions in a single unit. It is widely used in a variety of applications due to its reliable performance, durability, and ease of installation. Its latching and momentary switching capabilities, along with LED position indicators, make it a popular choice for various applications.
