42D36-12-2-AJS

Rotary switches are mechanical switches that have multiple positions. They are used for applications such as controlling a circuit, selectable voltage ranges and substituting for multiple ordinary switches. The type 42D36-12-2-AJS is a 12-position rotary switch made from a die cast frame with a chrome plated knob.The 42D36-12-2-AJS rotary switch utilizes a radius long travel wiper arm. This wiper arm operates along the perimeter of the switch interior, connecting the switch’s 12 positions with 12 independent terminal connections. The switch is further sealed against environmental contamination with a protective rubber boot. An optional sealing gland offers superior protection from dirt and dust.The 42D36-12-2-AJS rotary switch is a commonly used switch in a variety of electrical, industrial, and commercial applications. Common applications include: analog switch circuits, automation processes, transformers, DC current control, automotive audio systems, and industrial power switches. The switch can also be utilized to support a variety of control functions such as momentary contact, multiple contact closure and multi- circumstance switching.The primary advantages of rotary switches are that they are inexpensive and their electrical contact has low arcing when opened and closed. Additionally, their long life expectancy and ability to be reset or cycled make them ideal for arduous and abusive applications.The working principle of rotary switches is based on the rotor’s alignment with a number of contacts. When the switch is rotated, the rotor contacts or disconnects different terminals as it aligns with them. The contacts can be operated using a detented mechanism which achieves a positive click as the rotor moves from one position to the next.The 42D36-12-2-AJS rotary switch is a dependable electrical contact solution that is suitable for a variety of applications. Its durable construction and security seal makes it well suited for outdoor installation, and its low voltage requirements allow for easy integration into a variety of existing circuits.
