Um comprador em Bangladesh que procure um \u201cinterruptor tipo piano\u201d pode deparar\u2011se com dois produtos n\u00e3o relacionados: um interruptor basculante de parede para ilumina\u00e7\u00e3o e um interruptor eletr\u00f4nico DIP ou de bot\u00e3o, utilizado em placas de circuito. Encomendar na categoria errada n\u00e3o apenas implica o custo unit\u00e1rio; pode tamb\u00e9m causar problemas de encaixe das placas, classifica\u00e7\u00f5es inadequadas, atrasos na instala\u00e7\u00e3o e dificuldades na substitui\u00e7\u00e3o. Este guia trata do interruptor tipo piano ou basculante de parede, utilizado em instala\u00e7\u00f5es el\u00e9tricas fixas. Ele explica como comparar an\u00fancios no varejo e or\u00e7amentos de projetos, quais fatores influenciam o custo final, quais verifica\u00e7\u00f5es t\u00e9cnicas e locais devem constar em uma solicita\u00e7\u00e3o de cota\u00e7\u00e3o (RFQ) e por que um pre\u00e7o muito baixo exibido n\u00e3o constitui, por si s\u00f3, uma decis\u00e3o de compra completa.<\/p>\n

Resposta R\u00e1pida:<\/strong> O pre\u00e7o do interruptor de piano em Bangladesh<\/strong> n\u00e3o \u00e9 um valor nacional fixo. Uma compara\u00e7\u00e3o v\u00e1lida deve considerar a mesma fun\u00e7\u00e3o, tens\u00e3o e corrente nominais, tamanho do m\u00f3dulo, requisitos das placas, acabamento, garantia, quantidade, condi\u00e7\u00f5es de entrega e documenta\u00e7\u00e3o. Em 22 de setembro de 2026, as p\u00e1ginas acess\u00edveis diretamente da Walton apresentavam BDT 45 para as variantes unidirecionais da s\u00e9rie P1 listadas e BDT 52 para as variantes bidirecionais listadas. Estes s\u00e3o exemplos de varejistas com marca\u00e7\u00e3o de hora, n\u00e3o constituindo um padr\u00e3o de mercado nem um pre\u00e7o garantido. Para instala\u00e7\u00f5es fixas, os compradores devem tamb\u00e9m verificar os requisitos locais aplic\u00e1veis e solicitar evid\u00eancias pertinentes \u00e0 norma IEC 60669-1, em vez de optar exclusivamente pelo pre\u00e7o.<\/p>\n

O que significa \u201cinterruptor de piano\u201d neste guia de compras?<\/h2>\n

Aqui, um interruptor de piano \u00e9 um interruptor de balancim montado na parede, destinado a circuitos de ilumina\u00e7\u00e3o ou de instala\u00e7\u00f5es fixas semelhantes. O nome descreve a forma do acionador; ele n\u00e3o define a configura\u00e7\u00e3o do circuito, a classifica\u00e7\u00e3o, as dimens\u00f5es, a compatibilidade da placa, a constru\u00e7\u00e3o dos contatos nem o cumprimento das normas.<\/p>\n

A refer\u00eancia internacional relevante \u00e9 IEC 60669-1:2017<\/a>, \u201cInterruptores para instala\u00e7\u00f5es el\u00e9tricas fixas dom\u00e9sticas e similares \u2014 Parte 1: Requisitos gerais.\u201d O escopo abrange os requisitos gerais e as considera\u00e7\u00f5es de ensaio aplic\u00e1veis aos interruptores em instala\u00e7\u00f5es fixas. A mera cita\u00e7\u00e3o da norma n\u00e3o equivale \u00e0 comprova\u00e7\u00e3o de que um determinado produto foi ensaiado, certificado ou aprovado. O comprador deve solicitar informa\u00e7\u00f5es sobre a edi\u00e7\u00e3o, as cl\u00e1usulas, a configura\u00e7\u00e3o do produto, o laborat\u00f3rio e o n\u00famero do relat\u00f3rio que fundamentam a declara\u00e7\u00e3o do fornecedor.<\/p>\n

How should buyers compare Piano Switch Price in BDT?<\/h2>\n

A displayed pre\u00e7o do interruptor de piano em Bangladesh<\/strong> is useful only after the configuration is identified. On 22 September 2026, Walton\u2019s accessible P1-series one-way switch page<\/a> showed variants at BDT 45, while its two-way switch page<\/a> showed BDT 52. Prices may change and may exclude the faceplate, box, delivery, installation, or project discount.<\/p>\n

Record the seller, URL, check date, tax treatment, stock status, and delivery charge. Then calculate both switch-only and installed-set prices:<\/p>\n

Comparable BDT cost per point = switch mechanism + required module\/plate + box or accessory + allocated freight and tax + installation-related accessories.<\/em><\/p>\n\n\n\n\n\n\n\n\n\n\n

Which factors change the delivered price?<\/h2>\n

O Piano Switch Price<\/strong> for a loose mechanism is rarely the final project cost. Retail channels may price by piece, while distributors quote by carton or project volume. Imported or OEM supply adds MOQ, freight, customs-related charges, distribution, packaging, inspection, and exchange-rate exposure. Local stock may cost more initially but reduce lead-time and replacement risk.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

How should mechanism, contacts, plates, and finishes be evaluated?<\/h2>\n

A smooth rocker is not proof of electrical performance. Review positive operation, terminal design, conductor acceptance, visible workmanship, and sample consistency. Evaluate contact quality through documentation and relevant test evidence, not color, weight, or marketing language. For volume procurement, define an approved sample and incoming-inspection plan.<\/p>\n

Confirm whether the piano light switch<\/strong> is standalone or part of a coordinated frame-and-faceplate system. Record module width, gangs, box compatibility, fixing method, plate dimensions, finish, and color code. For phased projects, request a written approach to series continuity; a similar-looking part may not fit or match.<\/p>\n

What compliance checks apply in Bangladesh?<\/h2>\n

Procurement teams should separate three questions: whether the product is designed and tested to an appropriate technical standard; whether Bangladesh requires a current product approval, certification mark, import clearance, or other conformity step for that exact item; and whether the installation complies with the applicable electrical rules, utility conditions, and project specification.<\/p>\n

The Bangladesh Standards and Testing Institution publishes a mandatory-products list<\/a>. Because classifications can change, confirm the exact switch type with BSTI or a qualified local professional. Bangladesh\u2019s laws portal also provides the Electricity Act, 2018<\/a>; the project designer or licensed installer should identify the current installation requirements.<\/p>\n

Check rated voltage and current against the local supply, load, wiring design, and switching duty. A \u201c250 V AC\u201d listing does not establish suitability, local approval, or test compliance. Verify the datasheet and markings with the project engineer. IEC 60669-1 is a reference, not a blanket national certification.<\/p>\n

What should a buyer include in the RFQ?<\/h2>\n

An RFQ should make the piano switch<\/strong> mechanically, electrically, commercially, and legally identifiable. ABUK presents a wall switch and socket category<\/a> e um 1-gang rocker switch category<\/a> for sourcing review; use those pages to identify a product family, not to infer unlisted certifications, materials, ratings, or performance.<\/p>\n
