It can select among modes, signals or circuit configurations. The slider stays in the selected position. It is a through-hole PCB component with manual slider operation.<\/p>\n<h4>Features<\/h4>\n<ul>\n<li>Three stable positions<\/li>\n<li>Compact format<\/li>\n<li>For low-voltage circuits<\/li>\n<li>Announced service life: 10,000 cycles<\/li>\n<\/ul>\n<h4>Technical specifications stated in the source listing<\/h4>\n<ul>\n<li><strong>Maximum rated voltage:<\/strong> 30 V DC<\/li>\n<li><strong>Maximum rated current:<\/strong> 0.5 A<\/li>\n<li><strong>Contact resistance:<\/strong> \u2264 0.03 \u03a9<\/li>\n<li><strong>Insulation resistance:<\/strong> \u2265 500 M\u03a9<\/li>\n<li><strong>Insulation test voltage:<\/strong> 500 V AC for 1 minute<\/li>\n<li><strong>Approximate service life:<\/strong> 10,000 cycles<\/li>\n<li><strong>Mounting:<\/strong> through-hole PCB<\/li>\n<\/ul>\n<p>The 500 V AC value is a short-duration insulation test, not the switch\u2019s normal operating voltage. The source-listed maximum operating rating is 30 V DC, 0.5 A.<\/p>\n<h4>How it works<\/h4>\n<p>The slider moves an internal metal contact. Depending on its position, it connects the common terminal to another terminal or establishes a different contact combination. The exact connection diagram depends on the pinout of this version.<\/p>\n<h4>Identify the pinout<\/h4>\n<ol>\n<li>Set a multimeter to continuity mode before soldering the switch.<\/li>\n<li>Place the slider in the first position.<\/li>\n<li>Test combinations of pins and note which ones are electrically connected.<\/li>\n<li>Move the slider to the middle position and repeat the measurement.<\/li>\n<li>Repeat for the third position.<\/li>\n<li>Identify the common terminal or terminals.<\/li>\n<li>Draw a connection table before wiring the circuit.<\/li>\n<\/ol>\n<p>This procedure helps avoid wiring errors when the pinout is not printed on the component.<\/p>\n<h4>Example: selecting among three signals<\/h4>\n<ol>\n<li>Identify the common terminal with a multimeter.<\/li>\n<li>Connect it to the circuit input you want to control.<\/li>\n<li>Connect the selected contacts to the different signals or functions.<\/li>\n<li>Keep the voltage below <strong>30 V DC<\/strong> and current at or below <strong>0.5 A<\/strong>.<\/li>\n<li>Test each position before final soldering.<\/li>\n<li>Insulate exposed connections properly.<\/li>\n<\/ol>\n<p>For loads above 0.5 A, use the switch only as a control signal for a suitably rated relay, transistor or MOSFET.<\/p>\n<h4>Example: selecting a level<\/h4>\n<pre dir=\"ltr\"><code>Position 1 \u2192 Resistor R1 \u2192 Low level\nPosition 2 \u2192 Resistor R2 \u2192 Medium level\nPosition 3 \u2192 Resistor R3 \u2192 High level<\/code><\/pre>\n<p>With a suitable electronic circuit, this arrangement can select a speed, brightness, audio gain or reference value.<\/p>\n<h4>Safety precautions<\/h4>\n<ul>\n<li>Stay within the source-listed limit of <strong>30 V DC and 0.5 A<\/strong>.<\/li>\n<li>Do not connect this switch directly to 220\u2013230 V mains.<\/li>\n<li>Disconnect power before changing wiring.<\/li>\n<li>Check the pinout with a multimeter before soldering.<\/li>\n<li>Do not directly switch a motor or a significant inductive load.<\/li>\n<li>Use suitable protection for relays, coils and small motors.<\/li>\n<li>Avoid heating the pins for too long while soldering.<\/li>\n<li>Do not force the slider beyond its three positions.<\/li>\n<\/ul>\n<h4>Typical applications<\/h4>\n<ul>\n<li>Selecting one of three modes<\/li>\n<li>Audio circuits and input selection<\/li>\n<li>Lighting-level selection<\/li>\n<li>Speed control with a suitable circuit<\/li>\n<li>Arduino and robotics interfaces<\/li>\n<li>Battery-powered devices<\/li>\n<li>Electronic toys and controllers<\/li>\n<li>Prototypes and DIY circuits<\/li>\n<li>Small control panels<\/li>\n<li>Electronics training exercises<\/li>\n<\/ul>\n<p><small>Keywords: slide switch, 3-position switch.<\/small><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Compact maintained 3-position slide switch for low-voltage circuits.
