The contacts use copper alloy, ensuring reliable operation over a long period.
The "Mine-style Float Switch AR Type" is a general float switch used for liquid level control of heavy oil, light oil, edible oil, etc. The contact structure is 1a.1b, with one pole being a normally closed contact, allowing for versatile use such as alarm buzzers and indicator lamps. Additionally, the main body is housed in a cast iron case filled with insulating oil, which prevents the risk of arcs leaking to the outside when the metal contacts open and close inside. 【Float Switch Specifications】 ■ Product Name: Float Switch ■ Model: AR Type (Oil-filled Switch) ■ Contact Capacity: 250V MAX / 3A / 1a.1b ■ Contact Operation - Upper Limit OFF (a contact), Upper Limit ON - Upper Limit OFF (b contact), Upper Limit OFF *For more details, please download the PDF or feel free to contact us.
