ABSTRACT:
A hairsetter designed to heat a plurality of hair rollers to a predetermined temperature is provided with a plurality of sockets each intended to receive a single hair roller having a pair of electrical plug members axially extending from one end of the roller. The plug members are tapered along substantially their entire length and are formed as extensions of parallel longitudinally extending heat sinks engaging the sides of a PTC resistance heating element within the hair roller. Each socket is provided with a pair of contact pins. The upper portion of each pin is accessible through the top of the socket and the lower portion thereof is in contact with an electric wire to conduct power to the pin. The contact pins are separated by diametrically opposed ribs which interact with the tapered plug members to cause the hair roller to be automatically rotated as it as inserted into the socket so as to cause the plug members to firmly engage the upper portion of the contact pins.
