Abstract
A built-in indicator switch unit include an indicator and a switch within a casing so that the switch is operated by a pushing operation applied to a light-transmissible operation cover provided in the front side of the indicator. The switch is actuated by an operation mechanism which inverts the pushing force exerted on the operation cover to an opposite direction in response to the pushing operation applied to the operation cover. The indicator and switch are attached to a printed circuit board arranged in the casing, substantially in parallel to the front surface of the casing and projecting out at one end from the casing.
Claims12
A built-in indicator switch unit comprising:
- a casing made of an insulating material and having a substantially open front portion and a rear portion;
- a printed circuit board arranged in said casing, substantially in parallel to said front portion of said casing, said printed circuit including a part projecting outside said casing;
- an indicator attached to a front side of said printed circuit board in said casing and facing said open front portion;
- a switch attached to a rear side of said printed circuit board;
- a light-transmissible operation cover fitted in said front portion of said casing and movable in a direction of a pushing force exerted on said operation cover;
- and
- an operation mechanism for actuating said switch, said operation mechanism inverting said pushing force to a reversed force in response to a pushing operation applied on said operation cover, whereby said switch is actuated by said reversed force.
A built-in indicator switch unit comprising:
- a casing made of an insulating material;
- a light-transmissible operation cover fitted in a front portion of said casing so as to be movable in response to a pushing force exerted on said operation cover;
- a printed circuit board arranged in said casing, substantially in parallel to a front portion of said operation cover or inclined slightly thereto;
- an indicator having a plurality of LED-chip segments directly attached to a front side of said printed circuit board, said LED-chip segments being selectively activatable for display;
- a switch attached to a rear side of said printed circuit board in said casing;
- and
- an operation mechanism for actuating said switch, said operation mechanism inverting said pushing force to a reversed pushing force in response to a pushing operation applied onto said operation cover, whereby said switch is actuated by said reversed force.
A built-in indicator switch unit comprising:
- a casing made of an insulating material;
- a light-transmissible operation cover fitted in a front portion of said casing so as to be movable in response to a pushing force exerted on said operation cover;
- a flexible printed circuit board arranged in said casing, substantially in parallel to a front portion of said operation cover or inclined slightly thereto;
- an indicator having a second printed circuit board provided with a plurality of LED-chip segments mounted thereon, said second printed circuit board being directly soldered to a front side of said flexible printed circuit board;
- a switch attached on a rear side of said flexible printed circuit board in said casing, and
- an operation mechanism for actuating said switch, said operation mechanism inverting said pushing force to a reversed pushing force in response to a pushing operation applied onto said operation cover, whereby said switch is actuated by said reversed force.
A built-in indicator switch unit comprising:
- a casing made of an insulating material;
- a light-transmissible operation cover fitted in a front portion of said casing so as to be movable in response to pushing force exerted on said operation cover;
- a dot-matrix indicator and a segmental indicator both received in said casing and behind said operation cover;
- a switch received in said casing;
- and
- an operation mechanism for actuating said switch, said operation mechanism inverting said pushing force to a reversed pushing force in response to a pushing operation applied on said operation cover,
- whereby said switch is actuated by said reverse force.
