Abstract
A switch with an indicating mechanism having a movable indicating member which appears from and disappears in the upper end of a switch operating member to indicate the position of the switch, a receiving plate having an inclined surface on which the lower end of the operating member slides and being three-dimensionally disposed together with switch contact segments to effectively utilize the entire space inside.
Claims11
In a switch, an open top switch housing, a cover having depending walls seated on said switch housing, and an indicating mechanism comprising:
- a laterally tiltable actuating member having a longitudinally extending bore, said actuating member being disposed with its lower end in said housing and its upper end extending through an aperture in said cover;
- a movable indicating member slidably received in said bore;
- a switching member connected to the lower end of said actuating member and carried by said actuating member to switch movable contact segments into contact with contact segments fixed to said switch housing and extending through the bottom of said switch housing;
- a receiving plate disposed above said switch housing and received within the volume defined by said depending walls, said receiving plate having an inclined surface and being located above said switching member, supported on said housing and within said cover;
- a spring inserted between said actuating member and said indicating member;
- a longitudinal groove formed at the lower portion of said indicating member;
- and
- a vertically movable pin provided adjacent to the lower end of said indicating member, adapted to be pressed against said inclined surface by the action of said spring;
- whereby the upper end of said indicating member is made to be selectively visible or concealed by extending out of or being recessed within the upper surface of the actuator in accordance with the operating position of said actuating member.
In a switch, an open top switch housing, a cover having depending walls seated on said switch housing, and an indicating mechanism comprising:
- a laterally tiltable actuating member having a longitudinally extending bore, said actuating member being disposed with its lower end in said housing and its upper end extending through an aperture in said cover;
- a movable indicating member slidably received in said bore;
- a switching member connected to the lower end of said actuating member and carried by said actuating member to switch movable contact segments into contact segments fixed to said switch housing and extending through the bottom of said switch housing;
- a spring inserted between said actuating member and said indicating member;
- a receiving plate having an inclined surface at the center thereof and located above said switching member, said spring urging the lower end of said indicating member to make contact with and move along said inclined surface, said receiving plate being supported on said housing and within said cover;
- a connecting member disposed at the lower end of said actuating member, said connecting member being constructed to straddle said receiving plate and means connecting the lower end of said connecting member to said switching member;
- whereby the upper end of the indicating member is made to be selectively visible or concealed by extending out of or being recessed within the upper surface of the actuator in accordance with the operating position of said actuating member.
