Abstract

PURPOSE:To improve reliability while decreasing the number of contact springs by using a couple of contacts inserted into a common circuit as a common one, and operating one function switch by the operation of the other function switch while a contact couple state is maintained. CONSTITUTION:The hook switch h and line switch L of a DC cutting circuit D are substituted by a common one-make contact, and a calling, dial-originating and driving circuit B and an incoming circuit C are substituted by a common one-transfer contact. For said constitution, when the hook switch H and the line switch L are switched mutually, the switching should be done while a previous contact state is maintained. The figure shows an actual example of the hook switch H and the line switch L.
