Abstract
Abstract A safety stop switch assembly (10) for controlling a device such as an outboard motor includes a toggle switch having a switch arm (12). A clip (16) is held in place around the switch arm (12) by a spring arm (21). The clip (16) can be attached to the operator by a lanyard (17). When the operator is sufficiently removed from the device, the lanyard (17) will pull the clip (16) away from the switch arm (12) and turn the switch off. The switch arm (12) can be used to control the outboard motor with or without the use of the clip (16).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
A safety stop switch assembly comprising: (A) a base having a hole therethrough; (B) a switch attached to said base for controlling an electrically operated device, said switch including an actuator arm for operating said switch between an on and on off position, said actuator arm extending through said hole and having a pivot axis below the surface of said base; (C) a clip encircling said actuator arm; and (D) an attachment means for releasably attaching said clip to said base and holding said clip in position encircling said actuator arm regardless of the position of said actuator arm and permitting operation of said actuator irrespective of the presence of said clip, said attachment means holding said clip adjacent said actuator arm to prevent removal of said clip without moving said actuator arm to the off position.
Claim 2
Dependent Claim
137 words
A safety stop switch assembly comprising: (A) a base having a hole therethrough; (B) a switch attached to said base for controlling an electrically operated device, said switch including an actuator arm for operating said switch between an on and on off position, said actuator arm extending through said hole and having a pivot axis below the surface of said base; (C) a clip encircling said actuator arm; and (D) an attachment means for releasably attaching said clip to said base and holding said clip in position encircling said actuator arm regardless of the position of said actuator arm and permitting operation of said actuator irrespective of the presence of said clip, said attachment means holding said clip adjacent said actuator arm to prevent removal of said clip without moving said actuator arm to the off position.
Claim 3
Dependent Claim
18 words
The safety stop switch assembly defined in claim 1 wherein said attachment means is attached to said base.
Claim 4
Dependent Claim
26 words
The safety stop switch assembly defined in claim 2 wherein said catch means includes a spring arm attached to said base and biased against said clip.
Claim 5
Dependent Claim
33 words
The safety stop switch assembly defined in claim 3 wherein said spring arm is cantilevered and has a free end adjacent said actuator arm when said actuator arm is in the on position.
Claim 6
Dependent Claim
21 words
The safety stop switch assembly defined in claim 4 wherein said clip is pushed by said spring arm against said base.
Claim 7
Dependent Claim
24 words
The safety stop switch defined in claim 5 wherein said spring arm includes a projection near said free end, said projection facing said base.
Claim 8
Dependent Claim
30 words
The safety stop switch defined in claim 6 wherein said clip includes a first loop encircling said actuator arm and a second loop for attaching a lanyard to said clip.
Claim 9
Dependent Claim
40 words
The safety stop switch defined in claim 7 further comprising a pair of guides on opposite sides of said spring arm to limit the motion of said clip as said clip is removed from the position encircling said actuator arm.
