Rotary switches come in a variety of types and configurations, from basic single pole single throw (SPST) switches to complex multi pole multi throw (MPT) mechanisms. They are defined by their height, number of poles, number of throws and type of contacts. Everywhere from the back panels of audio equipment, to the control systems of airplanes and space ships, to the dials of old-style radios, rotary switches provide a dependable and economical solution for a wide variety of applications.

The 312-4T2E rotary switch is a singlepole double throw (SPDT) device, with a 4-position configuration. Depending on the number of positions, the 312-4T2E can have one or more center off positions. It is designed to switch lots of energy efficiently in spite of its small size, making it suitable for both small and large-scale applications.

The 312-4T2E switch is a popular choice for many applications, both common and obscure. From medical testing equipment, to elevators, to industrial-grade ovens, the 312-4T2E is the perfect switch to meet any modern switching challenge.

The 312-4T2E typically has two basic configurations: a center off position and a normally closed position. In the center off position, when the switch is on and no current is flowing, the center switch is in an "off" state, so that no current is passed to the other two contacts. In the normally closed position, the switch is on and a current flows in the "on" direction.

The 312-4T2E switch works by the rotational actuation of a spindle or cam. Depending on the number of poles, the number of contacts can be up to four. As each contact moves past the actuating mechanism, it is switched on or off. The direction of rotation for switching is usually clockwise, although it can be counterclockwise in some configurations.

As its name implies, the 312-4T2E has four positions in which it can be set. The four positions are labeled from left to right "off," "on," "first" and "second." Depending on the configuration, the switch can be set to any one of these positions with a simple turn of the spindle. The next position can be reached by repeating the process with the spindle.

The 312-4T2E is well suited for applications such as momentary or intermittent circuit control, switching in DC or AC power supplies and in multimedia applications. It is particularly useful in applications that require a short amount of time to shift from one circuit to another. This type of switch is well known for its long life and its ability to effectively switch high currents with a small amount of power.

For a variety of reasons, the 312-4T2E is an excellent choice for a range of consumer and industrial applications. Its small size and simple design make it reliable, cost-effective and versatile for a variety of projects. Its style and configuration is suitable for both small and large scale applications, making it a practical solution for any number of applications.
