Rotary switches vary in forms and sizes, depending on the displacement forces and the switching frequency. If you need to connect the supply voltage to the meter alternately, then to solve this problem you only need to purchase rotary switches in the Little Diode store. Such items also make it possible to measure the levels of main and standby generators and amplifiers. Rotary isolator switch is designed for direct current monitoring in electronic circuits. A dimmer switch, also available in our store, allows you to adjust the light and the level of illumination. Rotary switches are used in many consoles, including computer service consoles. Also, they widely can be applied in measuring equipment and other devices, allowing to choose the necessary position by their sequential search. Existing rotary switches are very diverse in their design; they have a different number of poles (slats) and are designed for a large number of positions: here you can find 3 position rotary switch, as well as other existing switches, including models with 4 position.
