Rotary switches are made up of a rotating actuator and one or more contacts that are arranged on a circular support. The actuator has a number of positions and can be connected to a number of different contacts in each position. When the actuator is moved, the contacts change position in order to carry out the desired circuit operation. The E4C1008S rotary switch is designed to provide reliable control of multiple-pole contact switching. It can be used in circuits with a variety of operating parameters, particularly in those applications where space is at a premium.

The E4C1008S consists of a stroked spindle operating a multiple-contact, multi-pole switch, housed in a polyamide case. The contact switch consists of a contact-seating mechanism, a contact bush, a contact-roller cage and a contact lifting-ring. The rotor is a single solid component which is mounted on the spindle, which is then connected to the contact body. The contact switch is operated by the rotating action of the rotor.

The contact switch is commonly used in applications that require the switching of four or more circuits simultaneously. The E4C1008S has eight poles and is capable of operating several different types of circuits. Some of the most common applications include microphone selection in PA systems, temperature or speed control switches, and audio mixer panels.

In terms of working principle, the E4C1008S is designed so that when the actuator is turned, the rotor rotates and positions itself between the contact points, which closes one or more of the contacts depending on the position of the actuator. The contact points are arranged in a series, so the switch is able to control the flow of electricity through the contacts. This can be used to control the power to various circuits, or to enable different sequences.

The switch is constructed to ensure high efficiency and reliable operation. The contacts have a special heat treatment process to provide a more durable contact interface. They are made of beryllium bronze and nickel silver for greater corrosion resistance. Additionally, the switches have a self-cleaning mechanism, which is designed to reduce the amount of dirt and dust that accumulates inside the switch.

The E4C1008S rotary switch is an ideal solution for the control of multiple-pole contact switching in a variety of applications. Its simple construction ensures reliable and efficient operation, while its small size makes it well-suited to applications where space is at a premium. It is an effective way to control the flow of electricity through circuits, enabling different sequences for a given application.
