Abstract: A bobbin or spool type hair curler having a cylindrical hair roller portion formed between a pair of opposing parallel flanges and provided with a pliable, integrally formed, cup-shaped closure member. The closure member is axially aligned to one of the end flanges of the spool shaped hair roller portion. The wall of the cup-shaped closure member extends away from the spool shaped portion and, after the hair is wound upon the spool shaped portion, the wall may be flipped substantially 180.degree. about its point of attachment to its corresponding flange in order to place the rim of the cup-shaped closure member proximate to the other flange to thereby retain the hair around the spool shaped portion. The invention additionally includes a method for curling hair with the aforementioned device and, in one embodiment the hair curler is provided with an axial throughbore and the invention further includes a method for heating same.

Abstract: A dual compartment magnetic switch interposed between a hand held electrical appliance and its electrical power input. The magnetic switch enables electrical power to be totally insulated from the electrical components within the appliance so that when the appliance is in the off position, user safety is enhanced.

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.
