Y20AP0373FP

Rotary Switches

Rotary switches provide a convenient and reliable way to connect one power source to one of many available circuits. They are often used in low voltage applications, like home and automotive applications, where one source of power needs to be connected to multiple circuits. The Y20AP0373FP rotary switch is especially designed for such applications and will provide reliable and accurate switching of one power source to one of many available circuits.

Application Field and Working Principle

Y20AP0373FP rotary switches are ideal for many wiring applications, including automobile electronics and home device control. The application field for the Y20AP0373FP includes but is not limited to: automotive electronics, instrumentation, bus system integrating lighting and sound, industrial control and home appliance technology.Y20AP0373FP rotary switches utilize a conventional construction arrangement, with windings wound as complete loops with start and end terminals, in each line. This arrangement eliminates potential hot spots and creates smooth transition from one power supply to the other. The Y20AP0373FP switch uses an internal disc to operate the rotary mechanism. This design is usually preferred because the switch is less prone to electromagnetic interference, resulting in a more reliable and accurate operation.

The internal disc of the Y20AP0373FP rotary switch is covered in metal contacts that rotate along with the shaft, allowing for either line to be traced by the metal contacts and complete the circuit. The input and output connection terminals are wired to the metal contacts, so when the switch is in operation, the metal contacts will trace the respective line and complete the connection until the switch is manually turned off.

The Y20AP0373FP produces a reliable, low-resistance switching action, since it has a large contact area and a high contact force. This type of rotary switch is easy to operate and has a long operational life, with low maintenance.In addition, the Y20AP0373FP rotary switch can be mounted onto an appropriately sized chassis or plate, in order to multiple switches to be lined up together, when operating several circuits.
