312-12

Rotary switches are electrical switching units that rotate through a predetermined number of fixed positions. They are also known as multiposition switches, as each switch typically moves through three or more positions. Commonly used in both residential and commercial applications, rotary switches are designed to achieve simple on and off switching and provide reliable and simple switching operations. The 312-12 rotary switch is one of the most popular switches in the rotary switch family.

The 312-12 rotary switch is a 3 pole, 12 position unit. It uses a contact connection to switch electrical power and provide a variety of configurations. The switch comes with a non-illuminated knob, but is also available as an illuminated switch with various light intensity levels. The 312-12 has positive stops that help ensure secure contact positioning and dependable switching action. It is also provided with two snap-on metal covers for knob protection.

The 312-12 rotary switch is available with a variety of connection options, such as screw terminals, spade terminals, and soldering lugs. A single pole, double throw contact system is the most common, but the switch is also available with a double pole, double throw contact system. The 312-12 has a maximum current rating of 10A (120VAC) and is UL approved.

In addition to the basic on and off switching applications, the 312-12 rotary switch is used for other purposes such as multiple position valve control, and for connecting audio/visual components in parallel, series or combinations of both. The switch is also frequently used in lighting and security circuits, providing a simple and convenient way to switch power on and off.

The working principle of the 312-12 rotary switch is relatively simple. When the user turns the switch to the desired position, it connects the incoming power through to one of the output terminals, which is then connected to the appropriate control device or appliance. The switch is designed to rotate easily, and the contacts are adjusted through a set of hex screws. Typically, the contacts are set so that the switch is closed when it is in the on position and open when it is in the off position.

The 312-12 rotary switch is suitable for a wide range of applications and can handle a variety of power levels. Its ability to control multiple circuits quickly and safely makes it an indispensable tool in both industrial and residential applications. With its simple design and straightforward operation, the 312-12 is an excellent choice for a wide range of applications.
