Frequently Asked Questions
Q: What does the 3-position (0-1-2) function mean on this changeover switch?
A: The three positions allow the operator to select between two separate circuit states (positions 1 and 2) or fully disconnect the circuit (position 0). This makes the SZW26-32 ideal for applications requiring manual circuit selection or source changeover, such as switching between two power feeds or controlling motor direction in industrial panels.
Q: Is this changeover switch compatible with both AC and DC circuits?
A: Yes. The SZW26-32/D303.3 is compatible with AC circuits operating at 50Hz–60Hz up to 440V and DC circuits up to 240V, making it a versatile choice for a wide range of residential, commercial, and industrial electrical setups.
Q: What are the mounting requirements for this switch?
A: The switch features a compact design with standard mounting dimensions, allowing for straightforward panel or cabinet installation without the need for special brackets or tools. Please refer to the product dimensions in the listing images for exact cutout and mounting hole measurements before installation.
