Wafer switches. Perpendicular outputs for printed circuits with a pitch of 2.54 mm. Non-short circuiting contacts. These additional wafers can be mounted on any PT series switching assembly detailed previously (30° indexing). The wafers are separated by a spacer 7.62 mm thick available to order separately. A shaft of a suitable length for the number of wafers ensures simultaneous switching of the assembly. Once fitted, this shaft is immobilised by a cross knob. The resultant assembly is secured by a set of M2 washers, nuts and studs. Models with no flat face.
