Rotary Switches

Rotary switches are a type of switch used for selecting a certain position in a circuit. They are mainly composed of a spindle or knob, a set of contacts, a supporting frame, and a central shaft which slides along a set of contacts when the knob is rotated.

The 42HS36-02-2-04S is a rotary switch mainly used in telecom, computer, instrument and audio circuits. It consists of a rotary actuator and center shaft which when moved in a circuit establishes closed contacts. It provides a hermetically sealed environment and a high mechanical strength with a long electrical life.

Application Field

The 42HS36-02-2-04S is mainly used in telecom and audio circuits. It is used in phone trunk lines and other telecom systems to control the switching operations. It enables the selection of correct circuits while having the capacity to handle large telecommunication line networks. It is also used in audio circuitry to switch from one input line to another. Additionally, it is also used in instrumentation as a user-friendly control for alarms, instrumentation controls and automation systems.

Working Principle

The working principle behind the 42HS36-02-2-04S is as follows: when the actuator is activated, the center shaft slides along the contacts and establishes a closed contact at the desired position in a circuit. This closed contact transmits the electric signals or digital data to the desired circuit where they are utilized. The rotary actuator is then used to rotate the switch and the switches select the proper station or circuit.

The 42HS36-02-2-04S is a two pole switch, meaning it has two pairs of electrical contacts. It allows for selection of two alternate positions where each position is associated with two contact points. Therefore, two complete electrical circuits are created by the two contacts of each switch. This switch type is highly suitable for use in applications where a wide array of alternate circuits needs to be selected.

The 42HS36-02-2-04S is a highly reliable switch which enjoys a number of protective features. It has a hermetic seal protection to prevent the occurrence of electrical faults due to dust or moisture in the surrounding environment. Furthermore, the switch offers a high mechanical strength to support contact operations and a long electrical life.

Conclusion

The 42HS36-02-2-04S is a rotary switch used in telecom, audio, computer, and instrumentation fields. It consists of a rotary actuator and center shaft which when moved in a circuit establishes closed contacts. This switch provides a hermetically sealed environment and a high mechanical stability with a long electrical life. This switch is an important component of telecom, audio and instrumentation systems and is highly suitable for applications where large array of alternate circuits needs to be selected.
