Frequently Asked Questions
Q: What are the electrical specifications of the IE-1111 micro-switch?
A: The IE-1111 is a snap-action micro-switch rated for 24VDC maximum, 5A contact capacity with single-pole switching. Dielectric strength is 1000VAC for 1 minute. Verify that your electrical system operates at 24VDC and does not exceed 5A load before ordering.
Q: Which electric lift truck models are compatible with the IE-1111 micro-switch?
A: The IE-1111 is designed for EPT series electric pallet truck assemblies and similar 24VDC platforms. Verify your equipment model and voltage system against the 24VDC rating and panel mount configuration before ordering.
Q: What is the mechanical life rating of the IE-1111 micro-switch?
A: The IE-1111 snap-action micro-switch has a rated mechanical life of 1 million cycles. Typical service life in electric lift truck applications is 2-4 years depending on activation frequency and environmental conditions.
Q: What materials are used in the IE-1111 micro-switch construction?
A: The IE-1111 features glass-filled nylon flame-retardant housing for durability, stainless steel plunger actuator for corrosion resistance, and silver alloy contacts for reliable electrical switching. These materials ensure consistent performance in electric lift truck control circuits.
Q: What symptoms indicate the IE-1111 micro-switch has failed?
A: Failed IE-1111 switches cause loss of function in the controlled circuit, intermittent operation, or no response to actuator input. If your lift truck control circuit does not respond when the switch plunger is pressed, the IE-1111 micro-switch requires replacement.
Q: Is the IE-1111 a direct replacement for original EPT series micro-switches?
A: Yes, the IE-1111 serves as a direct replacement for EPT series micro-switches, with equivalent 24VDC rating, 5A contact rating, and panel mount configuration. Verify electrical connections and mounting orientation match your original switch before ordering.
