Emergency switch provided with means to signify state of activation or inactivation thereof
View Patent ↗An emergency switch comprises a base on which an electrical circuit switch, and an indicator pin are mounted. An activation body is provided with an activation projection and a torsion spring and is movably mounted on the indicator pin. A trigger button is provided with a through hole and is fastened with a top end of the activation body. When the trigger button is triggered, the activation body is forced to move downwards along the indicator pin, so as to cause the activation projection to turn off the electrical circuit switch. A top end of the indicator pin is jutted out of the through hole of the trigger button to indicate that the emergency switch is in the state of activation.
1. An emergency switch comprising:
a base;
an indicator pin having a length and being fastened at a bottom end with said base;
at least one electrical circuit switch mounted on said base;
an activation body provided with at least one activation projection and a torsion spring wherein said activation body is movably mounted on said indicator pin in such a way that said activation projection is aligned with said electrical circuit switch; and
a trigger button provided with a through hole and fastened to a top end of said activation body in such a manner that said through hole is in alignment with said indicator pin, and that a top end of said indicator pin is received in said through hole of said trigger button wherein said top end of said indicator pin is extended out of said through hole of said trigger button at such time when said trigger button is exerted on by an external force so as to cause said activation projection of said activation body to turn off said electrical circuit switch.
2. The emergency switch as defined in claim 1 , wherein said top end of said indicator pin is different in color from said trigger button.
3. The emergency switch as defined in claim 1 further comprising a housing which is mounted on said base to shield said indicator pin, said electrical circuit switch, and said activation body.
