ABSTRACT:
A motor protection electric switch, and the like, in which contacts are opened and closed by means of a switch latch equipped with an "on" button and an "off" button, with the different positions of the "on" button indicating the switching state of the contacts. A two-armed blocking lever is rotatably mounted on a latch housing of the switch, and disposed between the contact member carrier and the "on" button. One arm of the lever is latched with the "on" button while the other arm thereof is supported at the contact member carrier as long as the contacts are not opened sufficiently far to open a circuit through the contacts of the switch.
