{"product_id":"bartell-20703-wire-assembly-66-safety-switch-oem-replacement-part","title":"Bartell 20703 Wire Assembly 66\" Safety Switch - OEM Replacement Part","description":"\u003cp\u003eThis 66-inch wire assembly connects the safety switch circuit on Bartell walk-behind power trowels, allowing the operator presence control system to cut engine power when the handle is released, a critical safety function that must be maintained in proper working order for compliant, safe machine operation. When this wire assembly becomes frayed, kinked, corroded, or fails to transmit the switch signal reliably, the safety interlock system may malfunction, preventing the machine from starting or causing unintended shutdowns during operation. Replacing this assembly restores the full-length routing integrity of the safety circuit from the handle-mounted switch down through the trowel frame, ensuring consistent electrical continuity across the 66-inch span.\u003c\/p\u003e\n\n\u003cp\u003eTechnicians servicing these machines should inspect the wire assembly for chafing against the frame, connector corrosion, and insulation cracking as part of any scheduled maintenance or whenever intermittent safety switch behavior is reported. A damaged or marginal wire in this circuit can produce symptoms including failure to start, unexpected engine cutoff, or a safety switch that appears functional when tested statically but fails under vibration during operation.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Bartell walk-behind trowel models:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eB424\u003c\/li\u003e\n\u003cli\u003eB430\u003c\/li\u003e\n\u003cli\u003eB436\u003c\/li\u003e\n\u003cli\u003eB446\u003c\/li\u003e\n\u003cli\u003eB446 MEGA-T\u003c\/li\u003e\n\u003cli\u003eBC436\u003c\/li\u003e\n\u003cli\u003eBC446\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Bartell Global OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Bartell","offers":[{"title":"Default Title","offer_id":43412760821808,"sku":"20703","price":94.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/20703.jpg?v=1784314104","url":"https:\/\/cce-industries.com\/products\/bartell-20703-wire-assembly-66-safety-switch-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
