Safe and simple to use, the 'BUZZ-IT' from Martindale is a real improvement for awkward sockets. It has an audible signal to tell you instantly whether or not the wiring is correct, and can also be used as a fuse finder, as the correct fuse is located when the buzzer stops. If there is a problem the pattern of LEDs indicates the fault. Any results other than three indicators lit and a continuous buzzing tone shows a fault condition. * Housed in a sculptured, flame retardant ABS case for easy insertion and removal * Size 65 x 65 x 47mm https://elecena.pl/product/27214427/martindale-bz101-buzz-it-audible-check-plug 2024-11-10 https://elecena.pl/product/27214427/martindale-bz101-buzz-it-audible-check-plug 2025-03-22 https://elecena.pl/product/27214427/martindale-bz101-buzz-it-audible-check-plug 2025-05-20 https://elecena.pl/product/27214427/martindale-bz101-buzz-it-audible-check-plug 2025-06-27 https://elecena.pl/product/27214427/martindale-bz101-buzz-it-audible-check-plug 2025-09-16 https://elecena.pl/product/27214427/martindale-bz101-buzz-it-audible-check-plug 2026-04-08
