Frequently Asked Questions
Q: What is the electrical rating for CR 078879 Crown OEM microswitch?
A: CR 078879 is rated for 25 amperes at 125 to 250 VAC with snap-action switching. This rating translates to 1 horsepower at 125 VAC and 2 horsepower at 250 VAC. The snap-action design provides positive contact engagement with minimal hysteresis.
Q: Where does CR 078879 microswitch operate in Crown M Series Stackers?
A: CR 078879 is integrated into the lower and raise electrical control circuits of Crown M Series Stacker pallet jacks. The microswitch detects load position, travel limits, or safety conditions, sending signals to motor relays or solenoids to control lifting and lowering functions.
Q: What does snap-action switching mean for the CR 078879 microswitch?
A: Snap-action means the switch contacts close and open with a rapid, over-center mechanical action independent of input force variation. This design minimizes electrical arcing, prolongs contact life, and ensures clean switching transitions in lift control circuits.
Q: What is the maximum switch operating force for CR 078879?
A: CR 078879 has a maximum switch operating force of 30 ounces. This relatively light actuation force suits control linkages and sensor mechanisms in Crown pallet trucks. Excessive force can damage internal springs and snap-action mechanism.
Q: Are there superseding or cross-reference part numbers for CR 078879?
A: CR 078879 is a Crown OEM microswitch with no available cross-reference or superseding part numbers. This Crown-specific part is designed for Crown M Series Stackers. Verify your equipment model and control circuit application before ordering to ensure correct fitment.
