A20605MNZQ Rotary Switches Application Field and Working Principle

Rotary switches, like the A20605MNZQ, are versatile electrical switching devices often used to select from a variety of different settings or configurations. With construction varying from basic single-pole and double-pole models, to complex multiple-pole, multiple-position structures, these switches are most commonly used in a wide range of consumer electronics, industrial applications, and audio equipment. The A20605MNZQ, in particular, is a six-pole, 20-position rotary switch with a positioning accuracy of 0.20°. This type of switch uses a pattern of contact blocks referred to as an “arrangement” or a “waferset” to control an electrical voltage or current through a variety of circuit configurations.

Generally, rotary switches similar to the A20605MNZQ are designed with a cylindrical body containing contact blocks that form its switching base. The contact blocks’ wiring is connected to the rotary switch’s pillars, and each contact block is connected with a wire to a source terminal. A control shaft is then fitted inside the cylindrical body to move the contact blocks, which will move in and out of contact accordingly. The control shaft is then connected to a “knob” or handle – this allows for the user to easily manipulate the switch as desired.

To apply the A20605MNZQ switch to its operating environment, firstly the switch should be wired according to the specific application. In order to ensure proper placement, each contact block should be positioned according to the miniature diagram. For example, when wiring a relay, the contact blocks should be connected to a common, normally open, normally closed, and a coil contactor. Following this, the rotary switch should be connected to a power supply, then the switch is ready to be tested.

Transitioning to the functionality of the A20605MNZQ rotary switch, as previously mentioned, the 20-position switch has a 0.20° positioning accuracy. This means that with every 0.20° turn, the switch will be in a new position. Moreover, this switch is designed with silver contacts, which offer a good contact reliability and low contact resistance. Operationally, these switches are designed to be rated for 24V at 0.3A, indicating the typical voltage and current that the switch can handle.

In conclusion, the A20605MNZQ is a six-pole, 20-position rotary switch that has a 0.20° positioning accuracy. This switch is typically used in a variety of applications that require reliable switching across power sources with a 24V rating and 0.3A current. In some applications, contact blocks may need to be wired in a specific patterns, and a power supply will also have to be connected before operation. In addition, silver contacts are fitted to this switch, which offer low contact resistance and improved contact reliability.
