However, if the internal lamp is specifically a 220V\/250V AC neon bulb, the light will not illuminate on 12V DC. If you specifically need 12V illumination, ensure you are using a 12V-rated DC switch variant.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How does the switch stay in the panel?\u003c\/strong\u003e\u003cbr\u003e\nA: The black plastic housing features flexible tension tabs on the sides. You simply drill or punch a 20mm circular hole in your panel, and the switch firmly snaps into place without the need for additional screws or mounting hardware.\u003c\/p\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × KCD-1 Round Red Illuminated Rocker Switch (QY602-101 W\/L)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOMSON ELECTRONICS","offers":[{"title":"Default Title","offer_id":49519594930414,"sku":"SWT-03663","price":19.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/ROCKER_SWITCH_ROUND_RED_KCD-1_QY602-101_W_L.webp?v=1788198317","url":"https:\/\/www.tomsonelectronics.com\/products\/kcd-1-round-illuminated-red-rocker-switch-qy602-101-w-l-3-pin-spst","provider":"Tomson Electronics ","version":"1.0","type":"link"}
