摘要： A switch for closing any low voltage electric circuit is disclosed. The invention resides in the provision of an elongated, flexible, dielectric element having a conductive wire, a terminal at either end, means at the median to attach it to a support member such as a wall, and a shaped nonconductive pull cord secured to its ends, and arranged to bring the terminals together to make electrical contact to close the circuit when tension is put on the pull cord.
