Abstract

A switch for controlling the current to a load combining an ON-OFF switch in series with a variable resistor. Switch has a housing which includes an actuator guided along a dimension of the housing. An opening through the actuator permits a portion of the regulator switch to pass through the actuator for operation. The actuator also includes a cam surface for operating the ON-OFF switch.

Claims

1. A switch assembly for controlling the current to a load combining an On-Off switch in series with a variable resistor the improvement comprising:

(a) a housing having a guide along a dimension thereof;

(b) an actuator being moved along said dimension of said housing, said actuator movement being defined by said guide of said housing and means for stopping movement of said actuator, said actuator further including an opening therethrough for permitting a first portion of an element of the variable resistor to pass therethrough and a second portion of the element of the variable resistor to remain accessible on one side of said actuator, said actuator also including a cam surface for contacting a portion of the ON-OFF switch for operation of the same, said opening and said stop means being sized and positioned to permit said operation of said ON-OFF switch.

2. The switch assembly of claim 1 in which at least a portion said actuator includes means for transmitting light along a dimension of said actuator and a source of light place adjacent said actuator.

3. The switch assembly of claim 2 in which said actuator includes a cavity and said source of light extends into said cavity, said cavity being formed to permit movement of said actuator without contacting said source of light.

4. The switch assembly of claim 1 which additionally comprises a cover for enclosing said actuator, said actuator being movable beneath said cover, said cover including an opening therethrough to permit movement of the element of the variable resistor which passes through said actuator opening.

5. The switch assembly of claim 4 which additionally comprises a slider connected to the element of the variable resistor said slide being movable in relation to said cover and being accessible on the exterior of said cover.

6. The switch assembly of claim 5 in which said actuator includes at least one leg which extends beyond said cover.

7. The switch assembly of claim 6 in which at least a portion said actuator includes means for transmitting light along a dimension of said actuator and a source of light place adjacent said actuator.

8. The switch assembly of claim 7 in which said actuator includes a cavity and said source of light extends into said cavity, said cavity being formed to permit movement of said actuator without contacting said source of light.
