220012831

Frequently Asked Questions

Q: What are the electrical specifications of the 220012831 micro-switch?
A: The 220012831 is rated for 250VAC maximum, 15A switching current, with SPDT (single pole double throw) contact configuration. The thermoplastic housing with stainless steel plunger actuator is designed for panel mount installation in electric lift truck control panels and circuits.

Q: What types of electric lift trucks use the 220012831 micro-switch?
A: The 220012831 is designed for electric lift truck applications requiring 250VAC, 15A snap-action switching. Typical uses include electric pallet trucks, stackers, and order pickers with control panels that require limit sensing, position detection, or safety interlock circuits. Verify your equipment control system voltage and current requirements before ordering.

Q: What does SPDT contact configuration mean for the 220012831?
A: SPDT (single pole double throw) means the switch has one movable contact that switches between two fixed positions. In the normal state, the contact is at one terminal; when actuated, it moves to the second terminal. This allows the switch to control multiple circuits or create logic-switching functions in the lift truck control system.

Q: Why does the 220012831 use a stainless steel actuator?
A: Stainless steel actuators resist corrosion and wear in warehouse and outdoor environments. The corrosion resistance extends switch life and maintains reliable mechanical operation when exposed to moisture, temperature fluctuations, or chemical exposure typical in material handling applications.

Q: How should the 220012831 be mounted in the control panel?
A: The 220012831 uses panel mount configuration, meaning the switch threads or clamps directly into the control panel cutout. Ensure the panel hole diameter matches the switch body diameter and that all electrical connections (terminals) are accessible from the rear of the panel for safe wiring.

Q: What is the expected lifespan of the 220012831 micro-switch?
A: Typical snap-action micro-switch lifespan is 500,000 to 1,000,000 mechanical cycles under normal operating conditions. Life decreases with rapid cycling, contact arcing due to electrical load transients, or mechanical shock. Monitor for sluggish actuation or intermittent electrical contact as signs of wear.
