  • Emergency switch provided with means to signify state of activation or inactivation thereof
    Patent number: 6930267
    Abstract: 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.
