Frequently Asked Questions
Q: What is the function of the micro-switch SKU 3143325?
A: SKU 3143325 is a lever-actuated micro-switch rated for 250VAC at 15A resistive load. It is used in electric lift truck control circuits to sense equipment position, operator inputs, load presence, or safety conditions. The momentary NO (normally open) contact closes when the lever is actuated.
Q: What are the electrical specifications of SKU 3143325?
A: Maximum rated voltage: 250VAC. Maximum rated current: 15A resistive load at 250VAC. Dielectric strength: 1000VAC for 1 minute between terminals. Contact type: momentary NO (normally open). Housing material: glass-reinforced thermoset plastic. Actuator material: stainless steel lever. Service factor: 1.0 for continuous operation.
Q: What lift truck equipment uses this micro-switch?
A: SKU 3143325 is used in control circuits for electric pallet jacks, hand trucks, and lift equipment from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers. Common applications include mast position sensors, limit switches, load sensing, and safety interlocks.
Q: How do I identify a failed micro-switch?
A: Symptoms of switch failure include inconsistent control response, controls not responding at all, or incorrect equipment behavior such as unintended mast movement or inoperative safety features. A visible crack in the housing, bent or frozen lever, or corrosion also indicates replacement is needed.
Q: What is the lifespan of SKU 3143325?
A: Micro-switches typically operate for 3-5 years depending on actuation frequency and environmental conditions. Frequent operation in damp or corrosive environments accelerates failure. Replace immediately upon malfunction to restore equipment control and safety function.
