An apparatus with remote control features for tripping off magnetothermal switches comprises at least one switch having a central core supporting trip-off linkages wherein a voltmeter coil is housed with each switch being connected to a respective one, e.g. a lamp, of user electric appliances. The apparatus also comprises a pushbutton control connected to each voltmeter coil in each magnetothermal switch for remotely and simultaneously operating the trip-off linkages to thus turn off simultaneously each electric appliance, while enabling function regaining by operating the corresponding switch locally.
