Frequently Asked Questions
Q: What is the contact rating and voltage specification for the CR 78879 switch?
A: The CR 78879 is rated for 25A at 125 to 250V AC with snap action microswitch operation. At 125V AC it delivers 1 HP and at 250V AC it delivers 2 HP. Verify your truck voltage before ordering to ensure compatibility.
Q: What is the operating force requirement for the CR 78879?
A: The CR 78879 microswitch requires a maximum operating force of 30 ounces. This snap action design activates reliably at consistent force levels, making it suitable for repetitive control applications on Crown electric lift trucks.
Q: Is the CR 78879 suitable for panel mount installation?
A: Yes. The CR 78879 features a plunger actuator and is designed for panel mount configuration. This setup is standard on Crown electric lift truck control systems. Cross-reference 078879 and 78879 confirm OEM equivalency.
Q: What enclosure material does the CR 78879 use?
A: The CR 78879 switch housing is constructed from thermoset plastic composite material. This provides durability and electrical insulation suitable for the electrical control environments found in Crown electric lift trucks.
Q: What are the cross-reference part numbers for the CR 78879?
A: The CR 78879 cross-references to CR078879, 078879, and 78879. These designations refer to the same original Crown switch component. When ordering, use CR 78879 for clarity.
Q: How do I know if the CR 78879 is failing or needs replacement?
A: Replace the CR 78879 if the switch fails to activate reliably, operates intermittently, does not hold electrical contact, or feels loose in the panel mount. Snap action microswitches do not have field adjustment. Replacement is the appropriate repair action.
