1. A safety lampholder comprising:
an insulating housing;
an insulating or electrically conductive lamp socket placed within one end of the housing;
an electrically shockproof means fully integrated within another end of the housing;
wherein the electrically shockproof means comprises two electrical connectors which are electrically coupled to a power supply; two electrical contactors which come into direct contact with a lamp body in engagement with the lamp socket, one contact at one end of at least one of the electrical contactors being movable resiliently and not directly electrically connected with the electrical connector corresponding thereto; a spring member fixed into a central portion of bottom of the electrically shockproof means; and a switching member having a lower part around which the spring member is fitted, an upper part which protrudes beyond a horizontal surface where at least one of the electrical contactors is located, and at least one protrusion with at least one side surface in slidable contact with one of the electrical contactors; and
wherein the electrical contactors, the electrical connectors and the switching member are disposed in the electrically shockproof means in a spaced manner by use of a partition member.
