SAKURA4D Vandal-resistant switches (like some other types of switches) can incorporate indicator lights or LEDs to indicate circuit activation, deactivation or fault conditions. The mechanical types often have gold-plated contacts that do not corrode, to allow reliable low-power switching. One advantage they have over mechanical contact-based switches is that they have no moving parts to wear out. Screw-on door-covered switches are used on public address equipment that is intended to be rented out to non-professional users. This page was last edited on 7 October 2024, at 16:02 (UTC).
