The A25 switch type has been designed for applications where available depths behind the mounting plates are limited and the switching programs require a large number of contacts. They are used when more than 12 switching positions are required. Typical applications are multi-step switches. Multi-pole step switches, instrumentation switches and control switches where depth problems exist. The A25 has 4 double-break contacts per stage which are controlled by two independent cams. The switch column can contain up to 12 stages representing a total of 48 contacts.
