Rotary Switches

A rotary switch is a switch operated by rotating a control dial or knob, which is connected to the contacts of a circuit by a central spindle. It is mainly used in various analog signal control applications and the like, such as lighting control, HVAC, and more. The 50CBPT90-01B02N rotary switch is one such example.

Description

The 50CBPT90-01B02N rotary switch is designed as a single pole double throw switch with a 1/2" knob. It has two positions and is rated at 3 Amps @ 125/250V AC or 6 Amps @ 125V AC. It can be used for either AC or DC applications, and is suited for printed circuit boards and panel-mounted applications.

The 50CBPT90-01B02N is a standard toggle switch with an On/Off action, where the switch changes the state each time it is rotated. The switch is designed with high contact forceable connections to ensure secure contact under vibration and shock, and it has an anti-rattle feature to prevent accidental contact change. The 50CBPT90-01B02N comes with a standard 10 MOhm contact resistance, and a high electrical reliability.

Application Fields

The 50CBPT90-01B02N rotary switch is used for a wide range of applications, such as in industrial, commercial, residential, and consumer electronics. It is widely used in audio and video equipment, appliances, power supplies, lighting control, HVAC, and other audio/visual systems.

It is also often used for switching power sources input and output, for controlling devices in automated machinery, for providing the current and voltage control in motors, and appliances, and in off/on applications that require a physical control.

Working Principle

The 50CBPT90-01B02N rotary switch works by a cam mechanism inside the switch. When the switch is turned in either direction, the cam rotates and moves a contact arm, which in turn makes contact with the circuit element closest to the knob. Depending on the switch model, the cam can move in one direction or two directions, while the contact arms can move in four basic directions.

The contact arms press against the circuit elements with enough force to ensure an electrical connection is made. The force is adjusted by a tension spring, which keeps contact pressure constant regardless of the number of times the switch is used. As a result, the 50CBPT90-01B02N is able to withstand shock and vibration without the need for repeated adjustment.

Advantages

The 50CBPT90-01B02N rotary switch offers several advantages. It has a low contact resistance and a high repeatability, making it suitable for applications involving frequent actuation cycles. Additionally, it is much easier to use than a toggle switch since it requires only a simple quarter-turn movement to change the position of the contacts.

The switch is also more reliable than other switch types, since it relies on a mechanical mechanism to operate. This makes it more resilient to electrical interference, and it also ensures better operation over an extended period of time.

Finally, the 50CBPT90-01B02N is also cost-effective and environmental friendly due to its high durability. It is rated for up to 1 million on-off cycles, reducing the need to replace broken switches, while it also consumes low power, helping to reduce energy costs.

Conclusion

The 50CBPT90-01B02N rotary switch is a versatile and reliable switch solution. It is easy to use, requires no adjustment, and offers superior durability even under harsh conditions. It can be used for a wide range of applications, and is a cost-effective solution with a range of advantages.
