Push-button sensor switch

摘要: A push-button sensor switch for controlling and indicating the output of an integrally mounted element is disclosed. The includes a frame having contact stack thereto which under control reciprocating plunger extending therefrom. hollow head housing attached to end reciprocal movement therewith. signal surface member extends into visible from window at housing. light sensitive resistor within recess in body therefore located given fixed distance stack. pair shutters are pivotally adjacent engaged by rotate response relative with respect surface, thereby alternately conceal expose sensor. terminals coupled contacts on controls sensor, function provide visual indication state including aliphanumeric indicia thereof.
