Frequently Asked Questions
Q: What are the electrical specifications of the 15804400 snap-action micro-switch?
A: The 15804400 features SPDT configuration rated for 10A at 125VAC and 5A at 250VAC. Terminal material is tin-plated brass with thermoplastic body construction. This switch is designed for panel mount applications in electric lift truck electrical systems.
Q: Which lift truck brands and models use the 15804400?
A: The 15804400 is compatible with electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify that your equipment voltage and circuit requirements match the 125VAC/250VAC rating before ordering.
Q: What does SPDT configuration mean and how is it used?
A: SPDT means Single Pole Double Throw. The switch has one common terminal that connects to either of two switched terminals depending on actuator position. This allows switching between two separate circuits or reversing polarity for directional control in lift truck functions.
Q: Why does the 15804400 have different ratings at 125VAC versus 250VAC?
A: Contact capacity is inversely related to voltage. At higher voltages, arcing characteristics increase contact erosion, limiting safe amperage. The 10A rating at 125VAC provides margin for inductive loads common in lift truck solenoids and motors, while 250VAC is limited to 5A for the same reason.
Q: How long does the 15804400 remain reliable with frequent switching?
A: Mechanical life expectancy for snap-action switches typically exceeds 1 million actuations. Electrical contact life depends on load characteristics. Resistive loads support longer life than inductive loads. In typical lift truck duty involving periodic directional or function control, the 15804400 should provide 5 to 7 years of service.
Q: What causes premature failure of the 15804400?
A: Common failure causes include exceeding rated amperage or voltage, switching inductive loads without snubber protection causing contact pitting, moisture ingress corroding tin-plated terminals, and mechanical failure of the snap-action spring mechanism from vibration or impact.
