ABSTRACT:
A momentary or latching mechanical switch wherein the externally threaded outer end portion of the housing has axially parallel external grooves each including a deeper portion, and the frame for the illuminated knob for a reciprocable plunger in the housing has elastic arms extending into the grooves and provided with protuberances received in the deeper portions of the respective grooves. The arms are separably held in their grooves by a nut which meshes with the end portion and is rotatable in a direction to expose the arms. The housing is inserted into the opening of a control panel from within before the arms of the frame are inserted into their grooves from the outside of the control panel, and the nut is thereupon rotated against the inner side of the control panel to confine the arms in their grooves and to urge the frame against the outer side of the control panel. The inner end portion of the housing is separably coupled to an adapter which separably supports several microswitches. A pin which is held in a slit-shaped opening of the housing and extends into a heart-shaped guide groove of the plunger is used when the switch is to function as a latching switch. When the pin is removed, the switch constitutes a momentary switch.
