Rotary Switches are electrical switches with multiple positions. Their terminals can be connected to an electrical circuit in different combinations, to select different outputs. The 59HS18-05A20N is a popular model of rotary switch designed for a wide range of applications. This article explores its features, applications and working principle.

Design Features

The 59HS18-05A20N is a multi-position rotary switch featuring a push-button, and behind-panel mounting. It has 18 positions, giving it 208 switching possibilities, with a maximum 4A coil current. The switch has double-pole double-throw (DPDT) contacts and a 2 pole rotary actuator with a 20-degree angle of rotation, allowing current to flow in two directions simultaneously. The body of the switch is built with tough, die-cast aluminum, and the terminals are composed of zinc alloy. The panel-mounted design makes the switch easy to install.

Applications

The 59HS18-05A20N rotary switch finds use in a number of applications. It is commonly used in industrial control systems for applications such as motor switching, temperature and pressure control, etc. It can also be used to switch power supplies and control lights and appliances in residential settings. It is also a popular choice for use in test equipment, such as voltage testers, amplifiers, and lightbulb testers.

Working Principle

The 59HS18-05A20N rotary switch works in the same way as other rotary switches. When the knob is rotated, the rotating arm makes contact with the internal terminals, closing the circuit and allowing current to flow. The number of positions determines the number of combinations, and the current rating of the switch determines the amount of current it can handle. The push-button allows for the switch to be reset when the power is cut off.

The 59HS18-05A20N rotary switch is an ideal choice for a variety of applications. Its small size, durable body and 208 possible combinations make it a great choice for both industrial and residential applications. It is easy to install, and its efficient design makes it a smart choice for controlling a wide range of electrical functions.
