Como você verifica um interruptor de luz para ver se está ruim?
Ligue e desligue a alavanca do interruptor.O testador deve acender quando a alavanca do interruptor estiver na posição ligada, mas não deve acender quando a alavanca do interruptor estiver desligada. Se não apresentar esse comportamento, isso indica que as conexões internas estão ruins e que a chave precisa ser substituída.

Que voltagem deve ser lida em um interruptor de luz?
A medição da tensão em um interruptor fechado (ON) fornecerázero volts. A medição em um interruptor aberto (OFF) DEVE fornecer 120 VAC. Você está lendo através da lâmpada.

Quanta resistência deve ter um interruptor?
De acordo com a Universidade de Washington, você deve ver uma leitura demenos de 25 ohms. Isso indica que existe continuidade elétrica através do interruptor. Desligue o interruptor e teste novamente. Você deve obter uma medida de resistência infinita.

Como você sabe se um interruptor de luz está ruim com um multímetro?
Usando seu multímetro configurado em ohms ou modo de resistência e colocando uma ponta de prova em cada terminal de parafuso, você pode testar se o interruptor de luz de pólo único funciona corretamente.Se o multímetro exibir resistência infinita (sem leitura), isso significa que seu switch não está funcionando corretamente e precisa ser substituído.

Como você testa se uma luz está conectada corretamente?
Toque uma ponta de prova do testador no terminal de parafuso quente (fio preto ou vermelho) e toque a outra ponta de prova no terminal neutro (fio branco). Se o testador acender, o aparelho ainda tem energia.

Como testar um interruptor de luz com um testador de tensão sem contato?
Teste um interruptor de luz
Toque as pontas de prova em um testador de tensão de contato nos terminais de parafuso na lateral do interruptor de luz para detectar uma corrente viva. Você também pode usar um testador de tensão sem contato segurando o testador cerca de uma polegada de distância dos terminais de parafuso para detectar uma corrente elétrica.
