TLDR
In this article, a movable contact on an arm is used to activate an external indicator to indicate overload or short circuit conditions, which activates an external sensor that responds to the contact.Abstract:
The switch has a movable contact [16] on an arm [15] that normally sits against a fixed contact [21]. The switch has two contact terminals [12,13] that are connected [23,28] to an arc extinguishing plate stack [24]. Operation of the movable contact is made by an electromagnetic actuator [18] with input from a bimetallic element [26] that responds to overload or short circuit conditions. Built into the terminal is an inductive sensor [30] that responds to the movable contact. This activates an external indicator.read more

Protective switch for protecting electrical or electronic systems in e.g. building, has switching mechanism coupled with transmission elements, which utilize part of mechanical energy of switching mechanism for generating wireless signals
TL;DR: In this paper, a switch (B) has a switching mechanism (M) for automatic switching off electrical circuit or individual loads, coupled with transmission elements (S1-S3) for generating specific wireless signals.
Patent
Junction box, has light conductor that is formed such that conductor deforms under deformation pressure from knob and sends and/or influences signal in deformed condition or changes signal in relation to undeformed condition
TL;DR: In this article, a light conductor is arranged in front of the knob of one of the switches or interrupters, such that the conductor experiences deformation pressure by the knob in the release position.
