Review CUMMINS Onan Limit Switch Contact Assembly Transfer Microswitch

The Cummins Onan 308-1235 microswitch is a vital component for the transfer system of Onan RV generators. This microswitch, manufactured by Cummins Power Generation, is designed to detect the generator's engine RPM and signal the transfer controller when the generator is running at the required speed.

This microswitch is a Contact Transfer type, which means it transfers the electrical contact from one set of terminals to another when the engine RPM reaches the predetermined level. It is crucial for proper generator operation, ensuring the power transfer from the generator to the RV's electrical system only when the engine is running at the optimal speed.

The 308-1235 microswitch is engineered with a robust design, featuring a hardened steel case that provides protection against environmental conditions. It is built to operate reliably in various temperatures and humidity levels, making it an excellent choice for RV applications.

This microswitch comes with a standard 1.25-inch mounting base, allowing easy installation on the generator's engine housing. The switch also includes two wire terminals with a 0.187-inch pitch, enabling secure and efficient wiring connections to the generator's controller.

The Cummins Onan 308-1235 microswitch is essential for ensuring a seamless power transfer between the RV's electrical system and the generator. Its reliable operation guarantees peace of mind while on the road or at the campsite, providing a constant power source for all your RV's electrical needs.

Please note that this microswitch is designed for use with Onan RV generators and should not be used with other types of generators. Always follow the manufacturer's instructions for installation and maintenance to ensure the longevity and optimal performance of the microswitch.

Buying a Cummins 308-1235 Onan limit switch contact transfer microswitch can be a useful addition to your generator system, providing better control and protection against overloading. Here are some pros and cons to consider before making a purchase:

Pros:

1. Improved safety: The microswitch helps prevent overloading by interrupting the power supply when the generator reaches its maximum capacity. This can help prevent damage to the generator and potential safety hazards.

2. Enhanced functionality: The transfer microswitch allows for seamless transfer of power from the generator to the load when the main power source is unavailable. This can be particularly useful during power outages or other situations where main power is disrupted.

3. Compatibility: The Cummins 308-1235 microswitch is specifically designed for use with Onan generators, ensuring a reliable and efficient fit.

Cons:

1. Cost: The microswitch may come with a higher price tag compared to some other switches on the market. However, the added safety and functionality features may justify the investment for some users.

2. Installation complexity: Installing the microswitch may require some technical expertise, particularly if you are not familiar with electrical systems. It may be best to consult a professional electrician or generator technician for installation.

3. Limited availability: The Cummins 308-1235 microswitch may not be readily available in all areas, making it necessary to order it online or through a specialist supplier.

Conclusion:

The Cummins 308-1235 Onan limit switch contact transfer microswitch offers improved safety, enhanced functionality, and compatibility with Onan generators. However, it may come with a higher cost and installation complexity compared to other switches. Ultimately, the decision to purchase this microswitch depends on your specific needs, budget, and technical expertise.

Recommendation:

If you rely heavily on your Onan generator for power and safety, the Cummins 308-1235 microswitch can be a worthwhile investment for the added safety and functionality features it provides. However, if you are on a tight budget or lack the necessary technical expertise for installation, you may want to consider alternative options or seek professional advice before making a purchase.
