Frequently Asked Questions
Q: What does "latching" or "self-lock" mean on this rotary selector switch?
A: A latching or self-locking rotary switch stays in the selected position after you turn the knob — it does not spring back to a default position like a momentary switch. This makes the LA38-11XD ideal for applications where the chosen setting must remain fixed until manually changed, such as power selector or mode control panels.
Q: What is the difference between 2-position and 3-position configurations?
A: A 2-position rotary selector switch allows you to toggle between two states (e.g. ON/OFF or Mode A/Mode B), while a 3-position version adds a center or intermediate state (e.g. OFF/Forward/Reverse). Choose based on how many control states your application requires.
Q: Is this switch compatible with standard 22mm panel cutouts?
A: Yes. This rotary knob switch is designed to fit standard 22mm diameter panel cutouts, making it a straightforward drop-in replacement or addition to existing control panels and enclosures that use the common 22mm mounting standard.
Q: What indicator lamp colors are available, and does the lamp require a separate power source?
A: The integrated pilot lamp is available in Red or Green. The lamp is powered through the switch circuit itself — please refer to the product wiring diagram included with your purchase to ensure correct installation for your voltage and configuration.
