Rotary Switches

Rotary switches are widely used in various industries and applications such as automotive, medical, industrial and consumer electronics. They are designed to be used as a control device to switch on and off electrical signals or devices. The most common type of rotary switch is the multi-pole rotary switch, which can be classified into single-pole, double-pole, or tri-pole rotary switches. The basic function of a rotary switch is to provide multiple electrical contacts with a single manual switch action.

The 42A36-01-2-05S rotary switch is a multi-pole rotary switch that is used for various industrial and consumer applications. This rotary switch has a smooth rotary action, providing three independent switches and a maximum line voltage of 370VAC/150VDC. It also boasts an IP67 rating, which makes it dust tight and water resistant.

Working Principle

The basic function of a rotary switch is to provide multiple electrical contacts with a single manual switch action. The 42A36-01-2-05S rotary switch utilizes a wafer-style rotary device with a unique segmental wheel design and multi-position active actuator for each switch pole. As the user rotates the knob, the actuator moves the wheel, making electrical contact with the internal switch contacts.

As the wheel turns, a cam follower tracks the wheel\'s movement and actuates an internal normally closed switch contact via a rocker switch. This changes the electrical state of the switch from open to closed, providing different electrical connections depending on the position of the wheel and the number of poles in the switch. This arrangement allows for multiple switch sets to be operated and monitored by the same switch.

Application Field

The 42A36-01-2-05S rotary switch is designed to be used in a variety of industrial, medical and consumer electronics applications. In industrial applications, the switch can be used as a main power switch or as a selector switch for selecting different operating modes in machinery or production line equipment. In medical applications, the switch can be used on patient monitor equipment such as heart rate monitors, blood pressure monitors and respirators. In consumer electronics, the switch can be used in a range of different products from TVs and radios, to audio and video equipment, to digital gaming systems.

The 42A36-01-2-05S rotary switch is a highly durable and reliable switch that is well suited for use in a variety of situations. Its multiple poles make it ideal for use in applications where multiple switch sets need to be operated and monitored by the same switch.
