Frequently Asked Questions
Q: What is the 3057742 micro switch, and what does it control?
A: The 3057742 is an SPDT (Single Pole Double Throw) micro switch rated for 5 amperes at 250 volts AC. It is designed for electric lift truck control circuits, typically used for tilt limit, drive inhibit, or safety interlock functions in industrial vehicles.
Q: What are the electrical specifications of the 3057742?
A: The 3057742 operates at 250VAC nominal, handles a maximum continuous current of 5 amperes, and has SPDT contact configuration (common terminal with normally open and normally closed paths). Contact material is silver alloy for reliable electrical conductivity and minimal voltage drop across the switch contacts.
Q: What electric lift truck applications use the 3057742?
A: The 3057742 is used in electric lift trucks and pallet jacks from manufacturers like Crown, Toyota, Raymond, and Hyster. Common applications include mast limit switches, drive circuits, and safety interlocks. Verify your equipment model and control circuit diagram before ordering.
Q: What does panel mount configuration mean for the 3057742?
A: Panel mount configuration means the 3057742 is designed to be fastened to a control panel or enclosure with the actuator extending through an opening. This keeps the switch body protected inside the panel while the actuator remains accessible to external mechanical contacts or linkages.
Q: What housing material is the 3057742 constructed from?
A: The 3057742 body is constructed from thermoplastic polymer enclosure material, which provides electrical insulation, chemical resistance, and impact protection in industrial vehicle environments. The thermoplastic material does not corrode and resists vibration-induced cracking.
Q: How do I verify if the 3057742 is compatible with my electric lift truck?
A: Check your lift truck wiring diagram and control panel schematic for switch specifications. The 3057742 is compatible if your circuit requires a 250VAC, 5A SPDT switch with panel mount configuration and silver alloy contacts. If your circuit diagram specifies different voltage or amperage ratings, do not use this switch.
