5 قطع منبه صفارة إلكتروني بيزو 95 ديسيبل صوت مستمر 12 فولت فتحة تركيب

these 5 buzzers are with me only as a reserve of exchange parts in the event of a breakdown in the intercom I only replace the defective parts used as a ring buzzer, I tested them with a 9 volt battery they work very well

It arrived well and relatively quickly. Now to test and mount them.

Everything perfect. Goods came faster than expected. 👍

One out of every 5 a bit stuffed falls off
