Rotary Switches

A rotary switch is a switch in which a circular or diametric rotating spindle acts as the switch actuator. It connects and disconnects the electrical equipment and devices which are wired to the switch terminals. Rotary switches are commonly used in industrial and commercial settings to control very large amounts of electrical power.

57M22-04A16S Application Field and Working Principle

The 57M22-04A16S is a type of industrial-grade rotary switch with 16 poles and 4 positions. It is a two-speed, two-position switch ideal for using in applications requiring switching of high power, large currents and/or high voltage. It is capable of switching currents up to 86 amps and voltages up to 150 volts. The 57M22-04A16S comes in three actuator styles: a knob, a single-point, and a multi-point actuator.

The switch operates by rotating the actuator, which then aligns and locks in a specific position. When the actuator is moved to a position, electrical contacts within the switch move to connect the desired terminals. The switch position is normally indicated by a white pointer or by a colored indicator in the center of the switch. The switch is designed to remain in its current position, and will remain locked in that position until moved by the actuator.

The 57M22-04A16S is resistant to shock, vibration and other extreme environmental conditions. It is UL and CSA certified, and is RoHS and REACH compliant. The contact arrangement of the switch is a bridge circuit, which ensures excellent contact and low resistance with high contact forces. The contact material is copper and tin plating on copper.

The 57M22-04A16S is suitable for use in a wide range of industrial applications, including industrial machinery, process pumps, ventilators, streetlights and more. It can also be used in automotive, aerospace and marine applications. The switch is also suitable for use in direct current (DC) applications, and can be used with medium-sized motors.
