Rotary switches are used to turn on and off electrical circuits, as well as for selecting different electronic functions. The 51CPT30-01B11S rotary switch is a 12-position rotary switch with a contact angle of 30°/index, with a 0.1” quick connect/solder lug terminal. It also has enhanced temperature range, with an operating temperature rating ranging from -20°C to +85°C.

A rotary switch has several contacts, arranged around a shaft, which the user can spin to make contact with any one of the contacts. When the user rotates the switch, the mechanical motion of the shaft makes electrical contact between the termination pins and whichever contact is currently being selected.

The 51CPT30-01B11S has twelve contacts, two of which are the common terminal and the start terminal. The first step of operation is to set the common terminal and the start terminal to the desired positions on the switch. These terminals act as reference points.

When the user rotates the switch, the position of the contacts is adjusted. As the switch moves over the contacts, connection is made between the switch terminal and whichever of the contacts it is over. In this way, it is possible to select which of the twelve available contacts will be used.

This type of rotary switch is commonly used for functions such as changing power levels, tuning circuits, setting radio frequencies, adjusting fan speed and selection of audio functions. It is also used in the fields of telecommunications, automotive, automotive, aerospace and defence.

The 51CPT30-01B11S is a highly reliable rotary switch, designed to withstand the rigours of harsh environments. It has a slow-motion charmer construction, to provide smooth operation, and a virtually lifetime of trouble-free use. It also has a dust and moisture-resistant seal, to keep out dirt and moisture, thereby improving the durability of the switch.

In summary, the 51CPT30-01B11S is a rotary switch that is commonly used for various applications such as power level changing, tuning circuits and radio frequencies, auto fan speed and audio functions selection. It is a highly reliable switch with a dust and moisture-resistant seal, slow-motion charmer construction, and a wide operating temperature range.
