A metal ball or mercury switch travels inside a sealed receptacle with two electrical contacts. The metal ball moves and makes touch with one of the electrical contacts when the switch is turned or moved, closing the circuit and initiating an action.\u003c\/p\u003e\n\u003ch3\u003eQ2: How does a shift switch SW200D operate?\u003c\/h3\u003e\n\u003cp\u003eThe power of gravity is used by a tilt switch SW200D to identify changes in orientation. When the switch is horizontal, the metal ball inside the container is in the centre and makes no touch with either of the electrical contacts. When the switch is tipped, the metal ball moves and makes touch with one of the contacts, closing the circuit and causing an action to be triggered.\u003c\/p\u003e\n\u003ch4\u003eQ3: What are some of the most frequent uses for a tilt switch SW200D?\u003c\/h4\u003e\n\u003cp\u003eTilt switches SW200D are frequently used in alarm systems, electrical toys, and vehicular uses, where they can sense changes in orientation, such as movement or vibration, and initiate an action. They're also used in commercial uses like level monitors, which sense the amount of liquid in a container.\u003c\/p\u003e\n\u003ch5\u003eQ4: What are the benefits of using a SW200D pivot switch?\u003c\/h5\u003e\n\u003cp\u003eOne of the benefits of using a tilt switch SW200D is that they are small and easy to integrate into electrical devices.

Compared to the other 'generic' micro-switches we carry, this one is higher quality and has better specifications. This is a basic micro switch for arcade and mini robots, and we don't have any detailed specifications for it so this switch is recommended for use with 30VDC and 250mA max. A great replacement for arcade controls.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eTECHNICAL DETAILS\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eOperating Frequency (mechanical): 120 operations\/min\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOperating Frequency (electrical): 5A-10~30 operations\/min\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eContact Resistance (initial): 100m Ω (Max.)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInsulation Resistance (at 500VDC): 100M Ω (Min.)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDielectric Strength (50-60Hz): 1000VAC RMS\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStorage Temperature: -25°C to 85°C\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStorage Humidity: At 40°C,Max. 85% RH (Max.)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eService Life (mechanical): Min. 10,000,000 operations\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eService Life (electrical): 5A - Min. 10,000 operations\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\n\u003cstyle\u003e\n.product-copy{line-height:1.7}\n.product-copy \u003e * + *{margin-top:1rem}\n.product-copy h2{margin:1.4em 0 .6em}\n.product-copy p{margin:0 0 1em}\n.product-copy ul,.product-copy ol{margin:0 0 1.2em 1.2em}\n.product-copy li{margin:.35em 0}\n.product-copy table{width:100%;border-collapse:collapse;margin:1.2em 0}\n.product-copy table th,\n.product-copy table td{border:1px solid #eee;padding:.6em .75em;text-align:left}\n.faq-list{margin:1.2rem 0 1.4rem}\n.faq{border:1px solid #e6e6e6;border-radius:12px;padding:.75rem 1rem;margin:.6rem 0;background:#fafafa}\n.faq summary{font-weight:600;cursor:pointer}\n@media (min-width:768px){ .product-copy{font-size:1.02rem} }\n\u003c\/style\u003e","brand":"Zippy","offers":[{"title":"Default Title","offer_id":45812671906081,"sku":"817","price":139.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/1491\/5617\/products\/micro-switch-premium-zippy-3-terminal-692.jpg?v=1689658617"},{"product_id":"switch-micro-with-roller-lever-3-terminal","title":"Micro Switch w\/ Roller Lever 3-Terminal - SPDT","description":"\u003c!-- META (paste these into Shopify → Search engine listing) --\u003e\n\n\u003cstyle\u003e\n .crx-scope{font-family:system-ui,-apple-system,Segoe UI,Roboto,Arial,sans-serif;color:#1f2937;line-height:1.65}\n .crx-scope h2{font-size:1.6rem;margin:0 0 .25rem}\n .crx-scope h3{font-size:1.15rem;margin:1rem 0 .35rem}\n .crx-scope p{margin:.45rem 0}\n .crx-scope .lead{font-size:1.05rem;color:#111827}\n .crx-scope .grid{display:grid;gap:12px}\n @media (min-width: 820px){.crx-scope .grid{grid-template-columns:1fr 1fr}}\n .crx-scope .card{border:1px solid #e5e7eb;border-radius:14px;padding:14px;background:#fff;box-shadow:0 1px 0 rgba(15,23,42,.04)}\n .crx-scope .chips{display:flex;flex-wrap:wrap;gap:8px;margin:.6rem 0 0}\n .crx-scope .chip{display:inline-flex;align-items:center;gap:6px;padding:.3rem .6rem;border-radius:999px;border:1px solid #e5e7eb;background:#f9fafb;font-size:.9rem}\n .crx-scope ul{margin:.35rem 0 .65rem 1.15rem}\n .crx-scope li{margin:.2rem 0}\n .crx-scope .specs{width:100%;border-collapse:collapse;margin:.5rem 0}\n .crx-scope .specs th,.crx-scope .specs td{border:1px solid #e5e7eb;padding:10px;vertical-align:top}\n .crx-scope .specs th{background:#f9fafb;text-align:left}\n .crx-scope .note{font-size:.95rem;color:#4b5563}\n .crx-scope .warn{border-left:4px solid #f59e0b;background:#fff7ed;padding:10px 12px;border-radius:10px;margin:.65rem 0}\n \u003c\/style\u003e\n\u003cdiv class=\"product-copy crx-scope\"\u003e\n\u003ch2\u003eMicro Switch with Roller Lever (3-Terminal: COM \/ NO \/ NC)\u003c\/h2\u003e\n\u003cp class=\"lead\"\u003eThis \u003cstrong\u003emicro switch with roller lever\u003c\/strong\u003e is a go-to part for \u003cstrong\u003elimit switching\u003c\/strong\u003e and position detection in robotics, 3D printers, CNC, and DIY automation.
