1NO1NC 3단 이중 래칭형 발광 회전 선택 스위치, AC 220V

FULL DESCRIPTION:

그 ACXION 1NO1NC Three-Position Double Latching Illuminated Rotary Selector Switch AC 220V is a front-panel rotary selector with a rectangular illuminated knob that holds its position in left, center, or right after the handle is released. Built from four modular components — knob, middle base, illuminated module, and contact assembly — the switch can be wired and serviced via screw terminals without specialist tools. The 1NO1NC contact configuration provides one normally open and one normally closed output simultaneously, covering the switching requirements of most three-state control circuit applications without additional relay logic. Standard silver-plated contacts are included; gold-plated contacts are available for corrosive or low-current signal environments. The built-in LED connects to an independent 220V AC pilot circuit with a rated lifespan of 50,000 hours. At ACXION, we test LED brightness consistency across production batches on illuminated selector switches — uneven indicator brightness across a panel is a common complaint from panel builders, and we address this at the assembly stage rather than leaving it to incoming inspection.

자주 묻는 질문:

Q1: What does “double latching” mean on a three-position rotary selector switch?
Double latching means the switch holds its position in all three locations — left, center, and right — after the handle is released. It does not spring back to any default position. This is the correct action for mode selection applications where the selected state must be maintained without the operator holding the switch.

Q2: What is the difference between this switch and the DC 24V version?
The only difference is the LED pilot circuit voltage. This version is rated for AC 220V illumination, suitable for panels where the control circuit runs at 220V AC. The DC 24V version is used in PLC-based panels where the control circuit runs at 24V DC. The contact configuration and mechanical specifications are identical — confirm your control circuit voltage before ordering.

Q3: When should I specify gold-plated contacts instead of standard silver-plated?
Gold-plated contacts are recommended for low-current signal circuits — typically below 100mA — where silver-plated contacts may develop surface oxidation that increases contact resistance over time. For standard industrial control circuits switching relay coils or PLC inputs at normal current levels, silver-plated contacts are sufficient. If your application involves dry circuit switching or instrument signal levels, specify gold-plated contacts when ordering.

Q4: Do you support OEM/ODM and wholesale orders for this switch?
Yes. ACXION supplies factory-direct from Jiangsu, China. We support OEM/ODM orders, wholesale bulk orders, and mixed-configuration batches. Contact us with your required quantity for pricing and lead time.
