<h2 data-start="217" data-end="269">🧪 Robust stainless steel for demanding media</h2>
<p data-start="270" data-end="773">The compact <strong data-start="284" data-end="327">mini float switches made of V2A stainless steel</strong> are ideal for applications with increased requirements – such as in <strong data-start="396" data-end="424">food processing</strong>, where hygiene and material durability are top priorities. Compared to plastic variants, stainless steel offers a particularly smooth, hygienic surface on which bacteria are significantly less likely to settle. V2A is also resistant to weak acids and alkalis – a clear advantage when used with aggressive media.</p>

<h2 data-start="780" data-end="821">⚙️ Durable thanks to precise manufacturing</h2>
<p data-start="822" data-end="1233">The shaft of the float switch is milled and turned from solid V2A stainless steel, making it extremely stable – even under constant stress. The float body is made of thin, rust-proof stainless steel sheet. Inside, a high-quality reed contact from Meder, which is waterproof and firmly soldered into the shaft, ensures permanently reliable signal transmission.</p>

<h2 data-start="1240" data-end="1279">🔁 Extremely durable & maintenance-free</h2>
<p data-start="1280" data-end="1638">Combined with low switching power – under 5 volts and 1 milliampere – the float switch achieves a service life of up to a <strong data-start="1425" data-end="1449">trillion switching cycles</strong>. This means no mechanical wear, no maintenance, and no failures. Once installed, the switch operates precisely and reliably over the long term – even in confined spaces.</p>

<hr data-start="1640" data-end="1643" />

<h2 data-start="1645" data-end="1703">🔌 Connection cable included</h2>
<p data-start="1704" data-end="2105">The float switch is equipped as standard with a <strong data-start="1754" data-end="1789">2.5-meter-long LiYY/PVC cable.</strong> According to the manufacturer, this cable is <strong data-start="1831" data-end="1856">temporarily waterproof, <strong data-start="1858" data-end="1873">flame-retardant, <strong data-start="1875" data-end="1896">self-extinguishing, and highly resistant to oils, greases, coolants, and lubricants.</p>

<hr data-start="2107" data-end="2110" />

<h2 data-start="2112" data-end="2161">🌊 Suitable for a wide variety of liquids</h2>
<p data-start="2162" data-end="2524">The float switch functions reliably with all liquids with a <strong data-start="2243" data-end="2266">density of 0.7 g/cm³ or higher. Depending on the installation position, it can be operated as a <strong data-start="2305" data-end="2323">normally open (NO)</strong> or <strong data-start="2329" data-end="2344">normally closed (NC)</strong> – simply by turning the float body. This step is not necessary for versions with an integrated changeover contact, as both functions are already integrated.</p>

<hr data-start="2526" data-end="2529" />

<h2 data-start="2531" data-end="2567">🧩 Installation with suitable accessories</h2>
<p data-start="2568" data-end="2959">For reliable operation, we recommend the optionally available <strong data-start="2639" data-end="2674">mounting bracket (item no. 300787). </strong>The mounting bracket ensures the float switch is positioned as vertically as possible, with a maximum deviation of 30° – so that the float can slide freely on the shaft without jamming or jamming.</p>
