Interchangeable electrical assembly with tactile switch and illumination device
An interchangeable electrical assembly provides a tactile switch that selectively opens and closes a circuit for operating myriad styles of illumination devices. The tactile switch detachably mates with, and regulates conduction of direct current to the illumination device. The tactile switch also provides tactile feedback of an operating position. A wire carries a 12 volt direct current into a switch housing. A conductive member receives the direct current. A cap receives a force to axially displace the conductive member while providing tactile feedback to the position of the conductive member. A contact pin operatively connects to the conductive member. A spring biases the conductive member to disengage from the contact pin. The cap selectively displaces the conductive member to engage the contact pin. An illumination device detachably mates with tactile switch, and includes a conducting shaft, an inverter for converting direct current to alternating current, and circuitry to generate illumination.
