Rotary switches are components used in many electrical control circuits and can range in complexity from simple momentary on/off control switches to complex multipled serially connected switch banks. The 093111-3-03N rotary switch is an example of a relatively sophisticated switch. This article will explore the 093111-3-03N’s application field and the working principles behind its functionality.

Application Field

The 093111-3-03N switch is a 3-pole, multi-position rotary switch. It is a great option for applications such as motor speed control, light dimming, electronic switches for audio and video devices, fan speed control and power delivery control. It is also suitable for applications that require multiple operating states and can provide more than one switching operation.

The 093111-3-03N switch has a 1/2” bushing size and 10 contact positions, numbered 1-10. It requires a minimum of 9 N-m to ensure proper contact performance. The switch can handle up to 16 A at 250 V AC, although its contact rating depends on the associated load. The dielectric strength of this switch is 1,000 Vrms minimum and the insulation resistance is 1,000 MΩ minimum at 500V DC. The maximum temperature for this switch is 70℃, and it is UL, CUL and CSA approved.

Working Principle

Rotary switches rely on the principle of “make before break” switching. This means that, when the switch is moved from one position to another, the new contacts will make contact before the previous contacts are broken. This ensures that no current is dropped or lost during the operation of the switch, which reduces electrical or magnetic arcing and minimises the risk of short circuits.

The 093111-3-03N switch is constructed using two interlocking rotor plates, two dielectric rotor bearings, stationary contacts and conducting pins. When the switch is turned, one of the rotor plates makes contact with one of the stationary contacts and the other rotor plate makes contact with another stationary contact, thus completing the circuit. The rotor plates are also spring-loaded, which ensures that the contacts are held in place and not jarred loose by vibration.

Conclusion

The 093111-3-03N rotary switch is a versatile switch suitable for a range of applications. Its reliable switching operation is integral to the functionality of many electric circuits, and its make-before-break function ensures that electrical current is not lost during switching operations. Its robust construction and UL, CUL and CSA approval combine to make it a dependable choice for many electrical applications.
