Frequently Asked Questions
Q: What does the 3-position setting on this rotary key switch mean?
A: The 3-position rotary key switch allows left and right selection, with the sequence: ON → OFF ← ON. This means the switch can be turned left for one circuit state, centered to the OFF position, or turned right for the alternate circuit state — ideal for reversible or dual-circuit control applications.
Q: Can the key be removed while the rotary switch is in the ON position?
A: No. A key safety feature of this rotary selector switch is that the key cannot be removed when the circuit is active (ON). The key can only be removed when the switch is in the OFF position, adding an important layer of security and preventing accidental activation.
Q: What panel cutout size is required for this 22mm rotary key switch?
A: This rotary key switch is designed for a standard 22mm panel cutout, making it compatible with most industrial and DIY control panels that use the common 22mm mounting standard.
Q: What contact configurations are available for this switch?
A: This switch is available with 1NO (normally open), 2NO (two normally open), 1NC (normally closed), and 2NC (two normally closed) contact configurations, giving you flexibility to match your specific circuit design needs.
